When you're under 40, retirement can feel like someone else's problem.
There's a career to build, travel to plan, maybe a mortgage to tackle. Thinking 20 or 30 years ahead isn't always exciting. But I genuinely believe your 20s and 30s are the most powerful financial decades of your life.
Not because you earn the most. But because you have time on your side.
Here are three financial moves I think can set you up for life if you make them early and stick with them.

1. Invest in ASX shares consistently, not occasionally
If I could give one piece of advice to someone under 40, it would be this: start investing in quality ASX shares or exchange-traded funds (ETFs) as soon as possible and do it regularly.
The share market is volatile. It always has been. There will be crashes, scary headlines, and periods where it feels like you made a mistake.
But history shows that broad share markets have delivered long-term returns in the high single digits per year. That doesn't mean 9% every year. It means ups and downs that average out over time.
If you're under 40, you likely have decades before you need to draw on your investments. That long runway gives you the ability to ride out downturns and benefit from recoveries.
Whether it's individual blue chips like Commonwealth Bank of Australia (ASX: CBA) or Wesfarmers Ltd (ASX: WES), or diversified ETFs such as a broad market fund, the key is consistency. Monthly investing builds discipline and removes the pressure to time the market.
2. Embrace dividend income and reinvest it
A lot of younger investors gravitate towards growth stocks, and that makes sense. But I think dividend shares deserve serious attention as well.
In Australia, many ASX shares pay fully franked dividends. That means you receive income plus franking credits, which can boost after-tax returns.
More importantly, dividends give you cash flow. In your early years, that cash flow should almost always be reinvested. Each dividend buys more shares. Those shares then generate more dividends. And so on.
Over time, that creates a powerful snowball effect.
It might not feel exciting at first. The amounts seem small. But a portfolio that starts paying a few hundred dollars a year can grow into one paying tens of thousands annually if you give it enough time.
That income stream can eventually fund lifestyle choices, reduce working hours, or even support early retirement.
3. Let compounding do the heavy lifting
Compounding is often described as the eighth wonder of the world. I genuinely think that's true.
Here's the simple version: when your investments earn returns, and those returns earn returns, growth accelerates.
In the first five years, most of your portfolio growth will come from your own contributions. It can feel slow and even frustrating. But after 10 or 15 years, the balance shifts. Investment returns begin contributing more than you do.
That's when things get interesting.
For example, investing $500 a month at an average return of 9% per year for 25 years can build a portfolio worth well over half a million dollars. Stretch that to 30 years and the numbers become even more powerful.
The earlier you start, the less you need to invest to reach the same end result.
Foolish takeaway
If you're under 40, you don't need a perfect strategy. You need a sensible one you can stick with.
Invest consistently. Reinvest dividends. Stay patient through volatility. And give compounding decades to work.
Do that, and you dramatically increase the odds that your future self will be financially secure, flexible, and free to choose how you spend your time.
