1. Waiting for the "perfect" time to start

Trying to time your entry usually means missing out. Because markets tend to rise over the long run, time in the market beats timing the market. The fix: start with a small amount now and invest regularly, rather than waiting for a perfect moment that never quite arrives.

2. Panic-selling when markets fall

Selling in a downturn locks in losses and often means buying back higher later. Volatility is the normal price of long-term returns. The fix: decide your plan in calm times, and hold through the noise unless your goals actually change.

3. Chasing hype and hot tips

By the time something is all over social media, the easy gains are usually gone - and hype often ends in painful drops. The fix: invest based on understanding, not FOMO. If you can't explain why you own something, that's a warning sign.

4. Not diversifying

Putting everything into one share or theme means one bad outcome can wreck your portfolio. The fix: spread across companies, sectors and regions - see our guide to building a diversified portfolio.

5. Ignoring fees

Fees feel small but compound against you for decades. A 1% difference in annual cost can quietly cost you a large chunk of your final pot. The fix: favour low-cost options and always check the annual fee before investing.

6. Leaving everything in cash

Cash feels safe, but inflation erodes its value over time. Being too cautious is its own risk. The fix: keep an emergency fund in cash, but invest longer-term money for growth.

7. Checking your portfolio constantly

Watching every wiggle amplifies anxiety and tempts you into bad decisions. The fix: set a sensible schedule to review - monthly or quarterly is plenty for a long-term investor.

8. Forgetting about tax

Where you invest changes what you keep. Ignoring tax-friendly accounts leaves money on the table. The fix: use wrappers like a TFSA or Retirement Annuity where they fit your goals.

9. Having no plan

Without a goal and a strategy, it's easy to drift, react and second-guess. The fix: write down why you're investing, your timeline, and how much you'll invest each month - then let consistency do the work.

Successful investing is less about being clever and more about avoiding unforced errors. Master your behaviour and you're most of the way there.
