You're Already an Investor. You Just Don't Know It Yet.
'Hey NHS investors...'
That's how I open every talk, every webinar, every small group session I run. And every single time, I watch a room full of doctors, nurses, physios and paramedics look back at me like I've said something slightly mad.
Because in their heads, I know exactly what's playing on loop.
"Investing isn't for me. It's risky."
"I don't earn enough yet. Maybe once I'm a consultant. Maybe once the loans are gone."
"There's genuinely nothing left after rent, bills and a well-earned takeaway on a post-nightshift Friday. What exactly am I supposed to invest?"
I've heard all three. Probably from you, if I'm honest — maybe all three in the same conversation. And here's what I need you to sit with, because it's the whole reason this blog exists
Every person thinking any of those thoughts is already an investor. They just haven't clocked it yet.
Not one day in the future. Not once they 'have more money'. Right now. Today. Whether they like it or not. You are the same.
Investing does not begin when you have a Trading212 app on your phone and buying occasional stocks with green arrows pointing up.
Investing begins the moment you earn a salary and handle money.
The trade you're already making, every single shift
Strip away the job titles, the rotas, the ward politics, the exam stress — and here's what's actually happening every time you clock in.
You are handing over hours of your one life. Your energy. Your sleep. Your attention. Your 20s or 30s, which you will never get back in exchange for anything. And in return, you receive an asset: CASH
That's not employment in the abstract sense we're taught to think about it. That's a trade. A direct exchange of the most finite, non-renewable resource you own — time — for a stored form of value.
So the question was never "should I start investing?" You're already investing — twice over, in fact. First, you invest your time and energy to earn cash in the first place. Then, the moment that cash lands in your account and you leave it sitting there, you're making a second investment decision: you're actively choosing to keep those earnings invested in the form of cash, as an asset. You've been making both of these investments since your very first pay cheque, whether you meant to or not.
The only question that actually matters is: what are you doing with the asset (cash) you got back for trading your time, working?
Cash isn't 'Safe'. It's just an asset class with a very predictable downside.
This is where I lose people in the room, so let's slow right down.
Most of us are taught, implicitly, that cash is the responsible option. The grown-up option. The safe harbour you retreat to once you've 'worked hard enough' to have some savings. Nobody ever frames it as risky.
But cash is not the absence of risk. Cash is simply an asset class — and like every asset class, it has a defined, measurable, near-guaranteed trend over time: it loses purchasing power.
Inflation doesn't negotiate. It doesn't wait for a convenient moment. It quietly, relentlessly erodes what a pound can buy you, year after year, regardless of how hard you worked to earn it.
Think about what that means in real NHS terms:
A tank of petrol that cost you £60 a few years ago now costs closer to £75 or £80.
The coffee you grab between theatre cases has crept up since you were an FY1.
The house deposit you're saving toward keeps receding, not because you're saving badly, but because the target itself is moving while your cash sits still.
That £15–£20 rise on the petrol alone means you now need to earn more just to fill the same tank — because the £60 you kept sitting in cash is still worth £60, or arguably less. You didn't get that gap for free. You have to trade more of your time, more shifts, more hours, just to earn enough to keep pace with a cost that moved without your permission.
Here's the sentence I want you to really absorb: if your wealth is sitting as cash, you are not preserving the value of your traded time — you are actively losing it.
You picked up a bank shift on your day off. You missed a friend's birthday, or a full night's sleep, or time with your kids, to earn that money. If it's parked as cash beyond what you actually need, it is quietly worth less with every year that passes — while you're not even watching it happen. That's a slow, invisible cost.
Warren Buffett put it plainly: 'Inflation is a far more devastating tax than anything that has been enacted by our legislatures. The inflation tax has a fantastic ability to simply consume capital.'
He wasn't talking to hedge fund managers when he said that. He was describing exactly what happens to the ordinary saver, like you and I, who never questions where their money sits.
The proof is already sitting in your own payslip
This is the moment in every talk where I watch the penny actually drop for people.
Your NHS pension is not a pot of cash sitting in a vault somewhere with your name on it, patiently waiting for you to turn 60-something. It is actively invested, right now, today, in the stock market — in equities, bonds, property and infrastructure, managed continuously by professional pension fund managers on your behalf.
Every single person reading this with an NHS pension is already a stock market investor. Has been for years. You never opted in consciously, you never sat down and chose it, and you've probably never once looked at what it's actually invested in — but the label doesn't change the reality.
So if you're the person quietly telling yourself 'investing isn't for me, that's not who I am' — I'd push back on that, gently but firmly. It already is who you are.
The NHS Pension Scheme decided that for you the moment you joined. The only genuine decision left on the table is whether you want to be an investor by accident, letting decisions happen to you — or an investor on purpose, understanding where your money sits and why.
Even your house is an investment
The same logic applies to the biggest purchase most of us ever make. You trade your time for a salary, then use that salary to buy a property. That’s an investment too.
You’re moving your money into an asset called 'a house 🏠'.
The aim is usually twofold. You get a place to live with more stability than renting, and you have the possibility that the property rises in value over the years. Your investment is stored in the value of the bricks and mortar.
A Renter is making a different choice, not a lazy one. Renting can mean fewer liabilities and lower upfront and ongoing costs. It can also free up more money to put into other growth assets, such as a stock portfolio.
Compared with a house, a stock portfolio is far more liquid, cheaper to run and much more flexible. You can add to it in small amounts, and you can sell part of it without selling the roof over your head.
Both are ways of choosing which assets hold the wealth you traded your time for.
Neither path is automatically right or wrong. Which one suits you can change at different points in your NHS career, and it depends on your personality and your relationship with risk too.
I’ll unpack the rent-versus-buy debate properly, through an investor’s eyes, in a future blog.
Watch this space, because the answer is rarely as simple as “renting is dead money” or “property always wins.”
It's not a personality trait. It's a skill.
Here's the reframe I think matters most, and I say this to every NHS colleague who tells me "I'm just not a numbers person."
You didn't come out of medical school, nursing school, or your AHP training already knowing how to cannulate, suture, catheterise or read an ECG. You learned it. Repetition, supervision, getting it wrong a few times safely, then getting it right.
Money is exactly the same. As Naval Ravikant puts it, making money is not a thing you do — it's a skill you learn. I'd go one step further for this audience: making AND managing money is not a thing you do, it's a skill you learn.
A lack of training is not a reflection of your intelligence — you're clearly capable of learning genuinely difficult things for a living. It's a reflection of a curriculum gap, nothing more. And gaps can be closed.
What 'On Purpose' actually looks like — in the right order
I want to be really clear about something, because this is where fear usually creeps back in. Investing on purpose is not about becoming a day trader. It's not about picking hot stocks off a WhatsApp group tip, or refreshing a trading app Trading212 between patients on a 6 hour long medical ward round. That's not investing — that's speculation wearing investing's clothes.
Real investing, done properly, with the right structure underneath it, is one of the calmest, lowest-drama things you can do with your money. But the order matters enormously.
Step one: build your 'Sleep-Well' Money first.
Before a single pound goes anywhere near the stock market, you need an emergency fund — genuine cash, held as cash, for the spending you already know is coming in less than 5 years AND the shocks you can't predict.
Things like:
A car that needs replacing
A house deposit you're actively saving toward
Wedding costs
A deposit for your children's school fees
Tutoring or other planned near-term costs
This is best held in high interest yield, flexible access, tax-efficient savings accounts. There's an art to handling your 'Sleep-Well' fund. You can perfect your emergency fund using the self-learning PDFs and calculators available to you on the MFA Money Toolkit 👇
Anything you'll need in the next one to a few years belongs in cash. This is the one place cash genuinely earns its keep — because for money you need soon, low volatility isn't a nice-to-have, it's the entire point.
You don't want a market dip deciding whether you can afford your four tyres.
Step two: everything beyond that gets to work.
Once your Sleep-Well Money and any known near-term spending is properly ring-fenced, any remaining wealth — money you genuinely won't need for many years — is exactly the wealth that shouldn't be left decaying in cash.
That's the pot that should be invested in a diversified, low-cost, tax-efficient portfolio, structured for growth over a long time horizon.
Given enough time, that growth doesn't just keep pace with inflation. History shows it outpaces it, by a meaningful margin, and compounding does the rest of the heavy lifting.
As Albert Einstein is widely credited with saying, compound interest is the eighth wonder of the world — "he who understands it, earns it; he who doesn't, pays it."
Whether or not he actually said those exact words, the principle holds up perfectly against every long-run market dataset we have.
This is also where risk management matters more than most people expect.
Managing risk well — through diversification, low costs, and a long enough time horizon — isn't the opposite of growth. It's what allows growth to actually happen without you panic-selling at the worst possible moment.
Get the risk right, and as Howard Marks would put it, 'the returns tend to take care of themselves.'
Wealth that pays you back for time you never gave
Here's the part that, for me personally, changed everything.
That pot of invested wealth — built quietly over years, simply by refusing to let money rot as idle cash — eventually reaches a point where it can start paying you an income. You sell a small slice of it as it grows, convert it back into cash, and it funds real life.
You didn't work an extra locum shift for that income. You didn't pick up an extra WLI clinic, an extra theatre list, or an extra bank shift for it. That money exists purely because, years earlier, you made a decision to let your money work as hard as you do.
That, to me, is the actual definition of financial independence. Not a magic number pulled from a spreadsheet. Not a finish line you cross once and never think about again.
It's the moment your assets start doing the trading of time for money on your behalf — so that you finally don't have to.
So — are you an investor? You already are.
Your NHS pension, the car you bought on finance, the house you bought with a mortgage proves it, whether you've ever looked at the statement or not. The cash sitting in your current account (invested as cash) proves it too, whether you like that answer or not.
The only thing left to decide is whether you keep investing in cash by default — letting inflation quietly take its cut of every hour you've ever worked, without you ever choosing that outcome — or whether you start learning & investing in other asset classes with inflation-proof, higher-growth potential, on purpose, with a proper tax-efficient structure, at a pace that actually fits the real, exhausting, yet rewarding NHS life.
I know which one I chose. I made that choice fifteen years ago, on an NHS registrar's salary, making just about every mistake in the book along the way — reading over 80 investment books in the process — so that you don't have to make the same ones.
You're already an investor. The only question left is whether you're going to learn the skill of being a good one.
