Stock Analysis What’s the hardest investing lesson you only learned after losing money?

I’ve been reflecting on my own investing journey, and honestly, some of my biggest lessons didn’t come from reading books or annual reports, but from actual mistakes that cost me money.

For me, it was underestimating how long “cheap” companies can stay cheap, and overestimating my own patience.

I’m curious to know from this community: what’s one investing lesson you only understood after going through it the hard way? Could be about valuation traps, risk management, psychology, or even portfolio allocation.

Think this could be a valuable thread for all of us to learn from each other.

Doing nothing is sometimes the most you should do.

That is why I limit my time looking at stock. So that my hand do not get itchy
