Big idea: Successful investing doesn’t have to be complicated. In fact, the most effective portfolios are often the least fancy.

Investing can feel overwhelming because there are so many choices. But most people don’t need dozens of ETFs or constant monitoring.

“One ETF is enough”

For many long-term investors, 1-3 broad ETFs — or an all-in-one ETF — is all they need to build wealth over decades.

Avoiding analysis paralysis

More choices often mean more hesitation:

  • “Which ETF is perfect?”
  • “Should I add another one?”
  • “What if I choose wrong?”

This is where many people get stuck — and never start at all.

But here’s the calm, grounding truth:
There is no perfect choice. There is only a good choice you can stick with.

Your job isn’t to build the fanciest portfolio.
It’s to build a portfolio you feel comfortable investing in regularly.

Why should I care?

Because simplicity reduces stress, fear, and second-guessing — and increases your chance of staying invested for the long term.

If it’s easier to just start with one ETF to get in the market, that works. You can always change your mind later.

Try this today

Imagine you could only invest in one ETF for the next two years. What would you choose?
