Your Future Self Will Thank You: The Psychology of Investing for a Person You Haven't Met Yet

Last week I was cleaning out a closet — the kind of deep clean you do once every three years when you finally accept that you’re never going to fit into those jeans again — and I found an old journal. It was from 2021. I flipped to a random page and found this entry:

“I really need to start investing. I keep saying I will. Maybe next month when things calm down.”

I sat on the floor and stared at that sentence for a long time. Because here’s the thing: I am that person’s future self. The person who wrote that entry was talking about me. They were hoping I’d be in good financial shape. They were counting on me to have figured it out.

And honestly? I’m glad past-me eventually did start investing. But I also know how close I came to being the version of “future me” who still hadn’t started. The version who would have read that journal entry with a pit in their stomach instead of a quiet sense of relief.

This post is about the weird, fascinating, and slightly unsettling psychology of why it’s so hard to invest for your future self — and how understanding that psychology can help you actually do it. If you’ve ever thought “I know I should invest, but…” then your brain is doing something very predictable, very human, and very fixable.

Let’s talk about it.

1. The Stranger in the Mirror: Why Your Brain Doesn’t Care About Future You

Here’s something wild that most people don’t know: your brain processes your future self the same way it processes a complete stranger.

This isn’t a metaphor. It’s neuroscience.

Dr. Hal Hershfield, a psychologist at UCLA, ran a series of now-famous fMRI studies where he scanned people’s brains while they thought about themselves in the present, themselves in the future, and other people. What he found was startling: when people thought about their future selves — the person they’d be in 10, 20, or 30 years — the brain regions that activated were the same ones that light up when thinking about a stranger.

Let that sink in. When you picture yourself at 65, your brain doesn’t file that image under “me.” It files it under “some random person.”

This has enormous implications for investing. When you have $200 in your pocket and you’re deciding between a nice dinner tonight and putting that money into your TFSA, your brain frames the choice like this:

• Option A: I get a delicious meal right now.
• Option B: Some stranger I’ve never met gets money in 30 years.

No wonder Option A wins most of the time. You’re not being irresponsible. You’re being human. Your brain is literally wired to prioritize you-right-now over you-later, because it doesn’t fully recognize you-later as you.

Hershfield’s research went further. He found that people who felt a stronger connection to their future selves — who could vividly imagine who they’d become — saved significantly more money. They made better financial decisions. They were more likely to invest consistently.

The problem isn’t discipline. The problem is disconnection.

2. Temporal Discounting: Why $100 Today Feels Like a Fortune and $1,000 in 20 Years Feels Like Monopoly Money

There’s a formal name for this phenomenon in behavioral economics: temporal discounting. It’s the tendency to value rewards less the further away they are in time.

Here’s a quick test. Which would you prefer?

• A) $100 right now
• B) $150 in one year

Most people pick A. That’s a 50% return in a year, which would make any investor drool, but it doesn’t feel like a good deal because the money is far away.

Now try this one:

• A) $100 in 10 years
• B) $150 in 11 years

Suddenly most people pick B. Same one-year wait, same 50% premium — but when both options are in the distant future, you think more rationally about it. The closer a reward is to “right now,” the more your brain inflates its value.

This is why Canadians who know they should be maxing out their TFSA or RRSP still find it hard to do it. The money you contribute today feels very real. That $7,000 you put into your TFSA? That’s a trip to Banff. That’s a new set of winter tires. That’s 1,400 large double-doubles at Tim Hortons (I did the math).

But the $50,000 that money could become in 25 years? That’s abstract. It’s theoretical. It’s Monopoly money. Your brain literally cannot process future wealth with the same emotional weight as present spending.

Temporal discounting is the reason “I’ll start investing next year” is the most common financial plan in Canada. Next year never has the same emotional urgency as right now. So it stays “next year” forever.

The antidote isn’t willpower. It’s systems — and we’ll get to that.

3. The Marshmallow Test for Adults: $500 Now vs. $2,000 Later

You’ve probably heard of the Stanford marshmallow test. Researchers put a marshmallow in front of a kid, told them they could eat it now or wait 15 minutes and get two marshmallows, and then left the room. The kids who waited tended to have better life outcomes decades later.

What nobody talks about is that adults face this exact test every single day — except the marshmallows are dollars and the waiting room is your entire financial life.

Here’s a real-world marshmallow test:

You have $500 sitting in your chequing account. You could:

• A) Spend it on a weekend getaway to Mont-Tremblant
• B) Invest it in XEQT inside your TFSA

Option A gives you memories, Instagram photos, and maybe a sore back from a bad Airbnb mattress. Genuinely enjoyable. No judgment.

Option B? At an average historical return of roughly 8% annually, that $500 grows to approximately:

• $1,079 in 10 years
• $2,330 in 20 years
• $5,031 in 30 years

That single $500 contribution — money you would have spent in a weekend — becomes over five thousand dollars by the time you retire. Tax-free if it’s in your TFSA.

I’m not saying never take the trip. Life is for living. But I am saying that every spending decision is a choice between present-you and future-you, and you should at least make that choice consciously instead of letting your brain’s default wiring make it for you.

The real challenge is that Option A gives you a dopamine hit this weekend. Option B gives you financial freedom in a few decades. Your brain has a very strong opinion about which one it prefers.

4. The Numbers That Change Everything: What Monthly XEQT Contributions Actually Become

I think one of the most powerful tools against temporal discounting is making the future concrete. Not abstract. Not “it’ll grow a lot.” Actual numbers.

So here’s what happens when you invest a fixed monthly amount into XEQT, assuming an average annual return of 8% (which is conservative given global equity historical performance, and what XEQT gives you exposure to — over 9,000 stocks across 49 countries):

Read that table slowly. Really look at the 30-year column.

$300 a month — roughly $10 a day — becomes $447,107. That’s less than what many Canadians spend on takeout coffee and lunch. And over 30 years, it turns into nearly half a million dollars.

At $750 a month, you cross the million-dollar mark. Inside a TFSA, that’s a million dollars completely tax-free.

These aren’t fantasy numbers. This is basic compound growth math. You can run your own projections with our XEQT calculator and see exactly what your specific contribution amount becomes.

The reason I show this table isn’t to guilt you. It’s to give your brain something concrete to attach to. Remember, your brain discounts the future because it can’t picture it. A table full of actual dollar amounts is harder to dismiss than a vague notion of “it’ll be worth more later.”

Every single dollar in that table is a gift from past-you to future-you. The only question is whether you’ll start writing those gifts.

5. Six Practical Techniques to Connect With Your Future Self

Okay, so your brain treats your future self like a stranger. That’s the problem. The solution? Make your future self less of a stranger. Here are six research-backed techniques:

Write a letter to your future self

This sounds cheesy. Do it anyway. Write a letter to yourself at 65. Tell them what you hope their life looks like. Ask them questions. Then — and this is the important part — write a letter back from your future self to present-you. What would 65-year-old you say? What would they beg you to start doing today?

I did this exercise two years ago. My future self’s letter started with: “Thank you for starting. I know it felt pointless at the time.” I cried a little. Then I set up an automatic XEQT purchase.

Use an aging app

Hershfield’s research actually tested this. People who saw age-progressed photos of themselves allocated more money to retirement savings. Download FaceApp or a similar tool, age your photo by 30 years, and set it as your phone wallpaper for a week. It sounds silly, but seeing that face makes future-you feel real in a way that abstract planning never can.

Name your investment accounts meaningfully

Don’t call your TFSA “TFSA.” Call it “Freedom at 55 Fund” or “Future Me’s Thank You Account” or whatever resonates with you. Wealthsimple lets you rename your accounts. When you see “Freedom at 55 Fund” instead of a generic account label, you’re less likely to raid it for a new TV.

Automate your investments

This is the single most important technique on this list. Automation removes your present-biased brain from the equation entirely. You can set up automatic XEQT purchases through Wealthsimple in about five minutes. Once it’s automated, future-you gets paid before present-you even sees the money. It’s like a direct deposit into your future life.

Calculate “future dollars”

Every time you’re about to make a discretionary purchase, multiply the price by 7 (a rough approximation of 30-year compounding at 8%). That $150 jacket? It’s actually an $1,050 jacket in future dollars. That $60 dinner? $420. You don’t have to skip every purchase — but knowing the true cost changes how you think about it.

Visualize a specific day in your future

Don’t think about “retirement” as a vague concept. Pick a specific Tuesday. You’re 67. You wake up without an alarm. What do you do? Where do you live? Who’s with you? What do you eat for breakfast? The more vivid and specific your future becomes, the more your brain treats that future person as you rather than a stranger.

6. How XEQT Makes the Future-Self Connection Easier

Here’s the thing about all the psychological barriers we’ve discussed — temporal discounting, the stranger problem, present bias — they all get worse when investing feels complicated. The more decisions you have to make, the more opportunities your brain has to say “let’s just deal with this later.”

This is exactly why I’m such a strong advocate for XEQT. Not because it’s the only good investment (it’s not), but because it removes almost every friction point between your present self and your future self’s financial security.

Think about what XEQT eliminates:

• No stock picking — You own over 9,000 stocks across 49 countries in a single ETF
• No rebalancing — iShares handles the allocation between Canadian, US, international, and emerging market equities automatically
• No market timing decisions — You buy regularly regardless of what markets are doing
• No complex portfolio management — One ticker. That’s it.
• No second-guessing — It’s the entire global stock market, not a bet on a single company

Every one of those eliminated decisions is a moment where present bias could have derailed you. Every one is a moment where your brain could have said “this is too complicated, I’ll figure it out next month.”

XEQT turns investing from a complex, ongoing project into a simple, automated habit. And habits are how you beat temporal discounting. You don’t rely on motivation or willpower — you rely on a system that runs whether you feel like it or not.

7. The Compounding Kindness Curve

We talk a lot about compound interest in personal finance. But I want to introduce a concept I think about often: the compounding kindness curve.

Every financial decision you make for your future self is an act of kindness toward someone who can’t yet thank you. And like compound interest, those acts of kindness compound.

Here’s what I mean:

• You invest $300/month starting at 25. That’s an act of kindness to your 55-year-old self.
• But your 55-year-old self, now financially secure, makes different decisions. They don’t stay in a job they hate because they need the paycheque. They don’t stress about money. They sleep better. They’re healthier.
• That healthier, less-stressed 55-year-old becomes a better partner, parent, and friend. They have energy for the people they love.
• Those relationships create a richer, more meaningful life at 60, 65, 70.

The $300/month didn’t just compound financially. It compounded into a better life across every dimension.

Conversely, the cost of waiting compounds too — but in the wrong direction. Every year you delay, future-you has to work harder, save more, and stress longer. The unkindness compounds just like the kindness does.

I think of it this way: your financial life is a long conversation between every version of yourself. 25-year-old you talks to 35-year-old you through the investments they make. 35-year-old you talks to 50-year-old you. And so on. The question is whether that conversation is generous or neglectful.

The beautiful part? You get to choose right now what that conversation sounds like.

8. What Your 65-Year-Old Self Would Tell You

I’ve spent a lot of time reading interviews with retirees — people who are actually living as their own “future selves.” The patterns in what they say are remarkably consistent. Here’s what your 65-year-old self would probably tell you:

“I wish I’d started earlier.” This is the number one financial regret among Canadian retirees, according to virtually every survey ever conducted. Not “I wish I’d picked better stocks.” Not “I wish I’d timed the market.” Just: I wish I’d started.

“The amount didn’t matter as much as the consistency.” Retirees who built wealth almost never did it with a single windfall. They did it with boring, consistent contributions over decades. $200 a month for 30 years builds more wealth than $50,000 invested once and then forgotten about.

“I worried about the wrong things.” Market crashes, recessions, corrections — they all felt like the end of the world at the time. In hindsight, they were speed bumps. The people who stayed invested through 2008, 2020, and every dip in between came out ahead. The ones who panicked and sold locked in their losses.

“Simplicity was the key.” Nobody at 65 says “I wish my portfolio had been more complicated.” They say the opposite. The simpler the strategy, the more likely they were to stick with it. This is why a single-ETF approach like XEQT resonates so strongly — it’s not just easy to start, it’s easy to maintain for 30 years.

“Thank you.” If you start investing now, your 65-year-old self won’t say “you should have done more.” They’ll say thank you. They’ll be grateful for every single automated purchase. They’ll be grateful that you read a blog post on a Saturday morning and thought, “Okay. Today’s the day.”

You can build a meaningful start with your TFSA — our TFSA millionaire strategy guide shows exactly how to build $1M tax-free using XEQT.

9. Bridging the Gap: From Knowing to Doing

If you’ve read this far, you understand the psychology. You know your brain treats your future self like a stranger. You know temporal discounting makes future wealth feel less real than present spending. You know present bias pulls you toward immediate gratification.

Understanding isn’t the hard part. Doing is.

So here’s my challenge to you: do one thing today. Not tomorrow. Not next month when things “calm down” (they never calm down). Today.

Pick one:

• Open a Wealthsimple account and deposit $150 to get your $25 bonus
• Set up an automatic monthly XEQT purchase — even $50 is enough to start
• Write a one-paragraph letter to your 65-year-old self and tape it to your bathroom mirror
• Rename your TFSA to something that reminds you who it’s for
• Open the XEQT calculator and type in your actual numbers

Just one. That’s it. Because here’s the secret that every behavioral scientist knows: the hardest part of any financial journey is the first action. Once you take it, momentum takes over. The automation handles the rest. And every month, without you having to think about it, future-you gets a little richer.

10. Every Dollar Is a Letter to the Person You’ll Become

I want to leave you with one image.

Every dollar you invest in XEQT is a tiny letter to your future self. It doesn’t say much on its own. Maybe it says, “Hey. I thought about you today.” But over time, those letters stack up. Hundreds of them. Thousands. And one day, decades from now, your future self sits down and reads them all at once — and the message they spell out is:

“You mattered to me before I ever met you.”

That’s what investing is, underneath all the charts and compound interest calculations and TFSA contribution room. It’s an act of care for someone you’ll become. Someone who will have your memories, your laugh, your weird habit of eating cereal at 11 PM. Someone who will be unmistakably, completely you — just older, and hopefully, because of the choices you’re making right now, a little more free.

Your brain might treat that person like a stranger. But you don’t have to.

Start today. Start small. Automate it so you don’t have to rely on motivation. And trust that the version of you reading this in 20 years — the one sitting in a paid-off house, sipping coffee on a Tuesday morning with nowhere they have to be — will be so, so glad you did.

They’ll probably find this blog post bookmarked somewhere. And they’ll smile.

Because past-you finally listened.
