Painful, but valuable lesson you won't repeat.
I wrote a humorous piece on how I lost ALL of my money in the stock market once. I was 10 :)
Your lessons learned are on point. Very simple rules to live by. Oh, and follow Warren Buffett
As for lessons, here’s what I learned:
Don’t try to time the market. No one can predict its future movements.
Don’t use margin. You can end up losing it all.
Don’t get FOMO and chase trends. Sometimes, the slow, boring investments do the best.
If you don’t know why you’re buying an asset, then you’re gambling.
Don’t put all your eggs in one basket. Diversify your assets.
