Let's do a little time-travel thought experiment, because it costs nothing and it might save you a fortune. Close your eyes — or don't, because you need to keep reading — and imagine yourself 20 years from now. Same face, a bit more grey, maybe a few more kind lines around the eyes. Now imagine that older you, sitting at the kitchen table, looking back at everything they did in all those years, and being asked a simple question. What past decision makes you proudest? And what one decision — the one you kept putting off — do you wish you'd made differently? Most people don't need to think about the second one for very long. You probably already know your answer. I know mine.
Here's what shocks me, every time I really sit with it: future me isn't annoyed about the mistakes I made. Mistakes are how you learn, and an honest mistake is just tuition. Future me is far more annoyed about the years I spent not even trying. The money I didn't invest because I was waiting for the perfect moment. The contributions I skipped because I thought they were too small to matter. The plan I kept writing in my head and never actually starting. Mistake me forgives easily. Procrastination me, on the other hand, gets a very stern look across the kitchen table. And I suspect your future self feels the same.
So here's the honest question this post is built around, and I want you to actually ask it of yourself. Not the version that's easy to wave away. The real one. Twenty years from now, sitting there with a lifetime of decisions behind you — will your future self thank you for starting early? Will they be grateful you started at all, even late? Or will they curse you, gently but sincerely, for not starting? That imaginary conversation is one of the best decision-making tools I know. It has no agenda, no broker, no influencer. Just you, being honest with yourself, across a span of decades. As always, none of this is financial advice — and what might be right for me isn't automatically right for you. But the 'future self' question? That one's just for you, and it's worth a look.
── The 'It's Too Late Anyway' Excuse, Gently Deconstructed ──
Let's deal with the biggest, laziest, most common excuse in the whole building-wealth playbook: 'it's too late for me.' Here's the thing about that phrase — it's rarely about your actual finances. It's about your feelings. 'It's too late' is how you tell yourself it's okay not to start, so you don't have to feel the small, uncomfortable pinch of doing something new. If I've learned one lesson in six decades with money, it's this: 'too late' is almost always a decision wearing a reason's clothes. And it's a decision your future self will be very unimpressed by.
The maths is actually on your side, and it's kinder than you'd think. Starting later with a bigger commitment can beat starting early with a tiny one — and starting at all, with almost anything, beats the perfect plan that never begins by an infinite margin (because zero, multiplied by any number of years, is still zero). You don't need a fortune to start. You need to start. A small regular amount, invested simply, given time, can become something surprisingly meaningful. Not guaranteed, not a promise — the value of anything can go down as well as up. But the opportunity to even have the conversation with future you? That only comes from starting.
And if you're worried you've left it so late that it's not worth the bother — stop. You are going to be that age anyway. This is not me being glib; it's me being logical. In twenty years, you will be twenty years older regardless of whether you spend those years investing or not investing. The only choice you actually get is whether the older you arrives with a growing portfolio, a quiet sense of 'I got on with it,' or with the same empty account and a slightly heavier feeling of 'I should have.' The years are going to pass either way. Might as well have them pulling for you.
── Meet the Version of You You're Building ──
Here's a confession from a 66-year-old: I used to think about my 'future self' like it was a different person, one I vaguely hoped would cope with whatever I handed them. It took me far too long to realise who that person actually is. It's me. It's just me, older, with my creaky knees and my longer view of things. And when I stopped treating future me as a stranger and started treating him as the same bloke — the bloke who'd have to live with whatever decisions younger me made — my whole relationship with starting changed.
Because here's the uncomfortable truth nobody puts on a poster: every month you don't start, you are making a decision. Not making a decision IS a decision — it's the decision to keep the status quo, to hand your future self the empty account and the 'oh well' shrug. And here's the kicker: your future self can't do anything about it. They're completely stuck with what you give them. They can wish, they can sigh, they can look at a calendar from 20 years ago, but they can't go back and nudge you to open that ISA. The only time present-you gets to help future-you is right now. That's the whole game. And it's a slightly terrifying, slightly wonderful realisation, because it means the power is entirely in your hands — and entirely in this moment.
I'll give you a picture I find genuinely useful. Imagine your future self writing you a letter, from twenty years out. What would they thank you for? 'Thank you for setting up that £50-a-month direct debit and leaving it alone.' 'Thank you for not panic-selling in the scary dip.' 'Thank you for buying less crap and investing the difference.' Now imagine the letter they'd write if you never started. 'I really wish you'd just opened the account. I'd give my left knee for that money to have had twenty years.' It's a silly exercise, I know. But I promise you, it focuses the mind more than any finance app. Don't leave your future self to write the wrong kind of letter.
── Starting Early vs Starting Big: The Honest Showdown ──
People tend to imagine the starting-early fanatics are telling a simple story: start young, get rich. It's not that simple, and I don't want to pretend it is. But there IS a genuinely powerful principle hiding in there, and it's worth understanding even if you're not young anymore. It's the principle of time doing the lifting. The earlier you start — even with a smaller amount — the more time your money has to sit there and do its quiet, compounding thing. Over long periods, that time is worth more than you'd guess.
Let me be honest about the trade-off, because I'm not selling you a fantasy. Starting early with small amounts is not automatically better than starting later with large ones. Someone who starts at 25 with £100 a month is not magically richer than someone who starts at 55 with £1,000 a month and a higher income behind them. The late starters are often earning more, and the bigger contribution can absolutely outrun the head start. I'm not going to pretend the maths always favours the youngster — because sometimes it plainly doesn't.
So what's the honest takeaway? It's not 'start early or you've failed.' It's 'start at all, and start as early as you reasonably can, because every year you get compounding working for you is a year you don't have to get back.' If you're young, that's a gift — use it. If you're not young, you still have years left, and those years are just as real as anyone else's. The worst outcome isn't starting late. The worst outcome is not starting at all. And the beautiful, boring secret is that starting at all — with a boring index fund, in a tax-efficient ISA or SIPP, on a direct debit you set up once — is genuinely quite easy. The hard part isn't the investing. The hard part is the starting.
── The Coffee Test: It's Not About the Coffee ──
Now let's have a laugh at the way the conversation about 'finding money to invest' usually goes, because it's worth a chuckle and it contains a real point. The advice brigade loves to tell you to give up your coffee. It's become a bit of a meme. 'Skipping one latte a day will make you a millionaire!' And honestly — no. Skipping the coffee alone won't do it, and the maths people use for that claim is often rubbish. But here's what the coffee meme gets RIGHT, in a way that's obscured by the clickbait. It's not about the coffee. It's about establishing that you're on the team. It's about proving to your future self that you're the kind of person who redirects a small bit of monthly spending into wealth-building instead of letting it vanish, unanswered, into the void.
The real point isn't 'stop enjoying your life.' Life is for living, and I'd never tell you to live on nothing for decades just so a brokerage app can show you a big number. The real point is that most of us spend money on things we barely register — and a chunk of that barely-registered spending, redirected automatically into a boring fund, could be quietly compounding for future you instead. You don't have to give up everything. You just have to catch a little of what's slipping through and give it a better home. Two less coffees a week, an automatic transfer set up once — that's not deprivation, that's just deciding to be on your own side.
And the reason I say 'don't leave it too late' about the coffee money (or the takeaway money, or the subscription money) is that small amounts, started early, are precisely where the magic lives. A couple of quid a week you barely notice, invested automatically from your twenties, can grow into something genuinely surprising by the time you're older — not because you were clever, but because time had a couple of extra decades to work. Start the habit now, whatever your age. Future you will be smug on your behalf.
── The 'You'll Be 70 Anyway' Line That Actually Works ──
I want to share the single most useful sentence I've ever heard for beating my own procrastination, because it cut through like nothing else. It's this: you're going to be 70 anyway. (Or 60, or 65, or wherever your horizon is — the exact number doesn't matter.) You're going to be that age whether you start investing or not. The question is just whether you arrive there with something you let grow, or with the same empty account and a 'what if.' And once I really let that sink in — once I stopped treating the future as avoidable and started treating it as certain — the excuse of 'waiting for the right time' collapsed. There is no right time. There is only now, and there's always a slightly later now, and the later you leave it the less time the compounding fairies have to do their staggeringly boring, staggeringly effective thing.
It's funny how the fear of starting usually turns out to be tiny next to the regret of not starting. I don't say regret lightly — it's a heavy word, and a heavy feeling, and I won't pretend I don't feel my own share of it for the years I frittered. But here's the reframe that saved me, and I hope it lands for you too: you don't have to be a financial genius, you don't have to start with a pile of money, and you don't have to know everything first. You just have to do one ordinary, slightly brave thing — open an account, set up a small direct debit, commit to leaving it alone — and then let time and the market do their ordinary, powerful work. The hardest step is the first one. Everything after that is just not stopping.
So, I'll leave you with the question, because it's honestly the whole point of this piece. Twenty years from now, when your older self looks back at this precise moment — this ordinary day when a slightly tired 66-year-old suggested you might want to start — what's the expression on their face? Is it gratitude for a decision that quietly changed things? Relief that you started at all, even though it wasn't perfect? Or is it the gentle, knowing, unshakeable curse of the road not taken?
I can't decide that for you, and I wouldn't want to. But I do know this: right now, while you're reading this, your present self holds the keys. Every day you don't start is a day your future self can't get back. And the version of you that's twenty years older deserves the fight. Not the stress, not the ruin-your-life-for-a-percentage thrill — just the calm, sensible, boring privilege of having given your money a couple of extra years to work for you.
Buy one less coffee. Invest the difference. Give it time. Start now — and I'll meet you at the kitchen table twenty years from now, both of us a little greyer, and I promise I'll be grinning. Invest. Wait. Repeat. Buy Less Crap. Invest Simply.
