Your Time Portfolio: The Investment Strategy No One Tells You About Before Retirement

For thirty years, David checked his pension statements religiously. He knew his projected retirement income down to the pound. He’d diversified his investments, maxed out his contributions, and planned for inflation. By every financial metric, he’d done everything right.

Six months into retirement, he sat in his living room at 10 AM on a Tuesday, financially secure and absolutely miserable.

“I just don’t know what to do with myself,” he told me over coffee. “I thought I’d love having all this time. But I wake up, and there’s just... nothing.”

David had spent decades building a financial portfolio that would support him in retirement. What he’d never done was build a time portfolio to tell him what he’d actually do with those years.

The Investment You’re Not Making

We obsess over retirement finances, and we should. But we treat retirement time like it’s going to sort itself out. Like the perfect life will just materialise once we’re free from work obligations.

It won’t.

Here’s the maths nobody mentions: full-time work consumes roughly 2,000 hours per year. When you retire, you don’t just get your evenings and weekends back. You get 2,000+ hours of empty calendar that used to be filled with meetings, deadlines, projects, and the thousand small structures that gave your days shape and purpose.

That’s not a blessing until you know what to do with it. Until then, it’s a void.

Think about it this way: if someone handed you £500,000 and said, “invest this wisely or it’ll be worthless in a decade,” you’d research, plan, and seek advice. You’d diversify. You’d think long-term. You’d take it seriously.

Yet we routinely walk into retirement with 40,000+ hours ahead of us and no investment strategy whatsoever. We just assume we’ll figure it out. We assume that wanting to relax will magically transform into a fulfilling life.

It doesn’t work that way.

The Time Portfolio Framework

Just as you spent decades building a financial portfolio, a successful retirement requires you to consciously build a time portfolio. This isn’t something to figure out after you’ve had your leaving party; it’s something to plan before you go.

Ask yourself: how am I going to invest my 2,000-plus hours of free time each year?

This portfolio needs to be diversified, just like your investments. And like any good portfolio, it needs different asset classes serving different purposes.

Your Growth Assets

These are the activities that challenge you, expand your capabilities, and give you something to work toward. They’re the equivalent of high-risk, high-reward investments; they require effort and might not all pay off, but they’re essential for keeping you engaged and evolving.

Growth assets might include:

• Learning a new language or musical instrument

• Taking up painting, photography, or writing

• Studying a subject you’ve always been curious about

• Developing a new physical skill such as woodworking, golf, or sailing

• Starting a small business or consultancy in your field

The key characteristic of growth assets is that they’re hard. They make you a beginner again. They require you to struggle, fail, and improve. This feels uncomfortable, which is exactly why many retirees avoid them. But discomfort is where meaning lives.

Malcolm, a retired engineer, took up ceramics at 67. “I was terrible at first,” he told me. “My hands didn’t work the way I wanted them to. Everything I made looked like a child did it. But that struggle, actually having to learn something from scratch again, that’s what made me feel alive. Work had become too easy. I’d forgotten what it felt like to be challenged.”

Your Income Assets

These are the activities that provide steady, reliable fulfilment. They’re your bonds and dividend stocks; they might not be thrilling, but they deliver consistent returns and give structure to your weeks.

Income assets might include:

• Volunteering regularly at a charity or community organisation

• Mentoring younger professionals in your field

• Serving on a board or committee

• Teaching or coaching

• Regular exercise classes or sports leagues

• Book clubs, religious communities, or social groups

The crucial word here is regular. These aren’t occasional activities; they’re commitments that create rhythm and routine. They give you reasons to get up, places to be, people expecting you.

Sarah retired from teaching and immediately signed up to volunteer at a literacy program two mornings a week. “It’s not about filling time,” she explained. “It’s about having somewhere I’m needed. On Tuesday and Thursday mornings, I have a purpose. People are counting on me. That structure makes the rest of my week feel less shapeless.”

Income assets also tend to connect you to other people, which turns out to be one of the most valuable retirement investments you can make.

Your Safe Assets

These are your relationships, family, old friends, and your partner. They’re the stable foundation of your portfolio, the assets you can count on when everything else feels uncertain.

But here’s the thing about relationships: they atrophy if you don’t invest in them. You can’t just assume they’ll be there when you finally have time for them.

Safe asset investment looks like:

• Actually planning time with friends, not just saying “we should get together”

• Being present for grandchildren’s lives in meaningful ways

• Deepening your relationship with your partner (who’s also adjusting to having you around all day)

• Reconnecting with old friends or distant family

• Making new friends through shared activities

James assumed retirement would mean more time with his wife. What he didn’t anticipate was that she had her own life, rhythms, and routines that he was now disrupting. “We’d been living parallel lives for years,” he admitted. “She had her friends, her activities. I thought we’d just naturally spend more time together, but I hadn’t actually thought about how or what we’d do. I was just... there. In her space. And neither of us knew how to navigate it.”

Safe assets require maintenance. The friendships you’ve neglected for twenty years while climbing the career ladder won’t magically revive themselves. Your adult children have their own lives and might not need or want you around as much as you’d imagined. You need to actively invest in these relationships before you’re desperately lonely and they’re your only option.

The Diversification Principle

Here’s where most people get it wrong: they over-invest in one asset class and wonder why they’re unhappy.

You can’t build a time portfolio that’s 100% growth assets. You’ll burn out. Learning Italian while also taking up tennis, while also starting a consultancy, while also writing a novel sounds ambitious, but it’s exhausting. You need steady income assets, too, the reliable pleasures that don’t require constant effort.

But you also can’t build a portfolio that’s 100% safe assets. Spending all your time with family and old friends feels comfortable, but it’s stagnant. You need something that pushes you, something where you’re still becoming rather than just being.

And you definitely can’t build a portfolio with no income assets, no structure, no rhythm, no regular commitments. That’s how you end up like David, financially secure and completely adrift.

The right mix is personal, but the principle is universal: diversification matters as much for your time as it does for your money

The Compounding Effect of Early Planning

Here’s the advantage of planning your time portfolio before retirement: compounding.

If you start learning Spanish two years before you retire, you’ll walk into retirement with a skill that’s already developing rather than starting from zero. If you begin volunteering one morning a week while still working, you’ll have established relationships and routines that carry forward. If you nurture friendships throughout your working years, you won’t be trying to rebuild a social life from scratch at 65.

The people who thrive in retirement are the ones who started investing in their time portfolio years before they left work. They didn’t wait until they had infinite free time to figure out what they wanted to do with it.

Portfolio Management Isn’t One and Done

Your time portfolio, like your financial portfolio, needs regular rebalancing.

What fulfils you at 65 might bore you at 75. Your health changes, your energy changes, and your interests evolve. Activities that once felt like growth assets become income assets as you master them. Relationships that were safe assets might require more intensive care as people age or circumstances shift.

You need to check in with yourself: Is this still working? Am I still growing? Am I still fulfilled? Do I need to shift my allocation?

And just like with financial portfolios, you need to be willing to cut losses. That hobby you thought you’d love but actually hate? Quit. That volunteer commitment that’s draining you instead of energising you? Step back. The friends who make you feel worse about yourself? Invest less time there.

What Happens When You Don’t Plan

I’ve watched too many people walk into retirement with no time portfolio, and the patterns are depressingly consistent.

The first few weeks feel like a holiday. Freedom! No alarm clocks! No meetings! They sleep in, putter around, maybe take a trip. It’s glorious.

Then the novelty wears off. The days start to blur together. They watch more television than they meant to. They spend hours scrolling through news or social media. They find themselves at loose ends, vaguely anxious, unable to settle into anything.

Some try to fill the void with busy-work, endless house projects, over-managing adult children’s lives, and making problems where none exist just to have something to solve. Others slip into passivity, waiting for life to happen to them instead of actively creating it.

The ones who struggle most are the ones whose identity was completely wrapped up in their career. Without the title, the authority, and the purpose that work provided, they don’t know who they are anymore. And without a plan for who they want to become, they just drift.

The Question You Need to Answer Now

If you’re anywhere near retirement—five years out, ten years out—ask yourself this:

When work no longer fills my time and defines my identity, what will?

Not in some vague, “I’ll figure it out” way. Actually. Specifically. What will you do with 2,000+ hours per year?

What will challenge you? What will provide steady fulfilment? What relationships will anchor you?

You don’t need to have it all figured out. But you need to start thinking about it with the same seriousness you’ve brought to your pension planning. Because all the money in the world won’t make you happy if you don’t know what to do with your time.

Your time portfolio is the investment that determines whether retirement feels like freedom or feels like exile. Whether you wake up excited about the day ahead or dreading the empty hours stretching before you.

You’ve worked hard to ensure you can afford retirement. Now do the work to ensure you’ll actually enjoy it.

Start investing now. Your future self will thank you.

What’s in your time portfolio? What are you building toward, not just saving toward? These are the questions that matter as much as your pension balance—maybe more.
