“If you have trouble imagining a 20% loss in the stock market, you shouldn’t be in stocks.”
The stock market, just like life, has its ups and downs. You have to be prepared for those ups and downs, not write the downturns off as ‘not in your vocabulary’. I wouldn’t recommend being pessimistic, but a healthy does of realism does help.
Frustrating as it may sound, you have to roll with the punches. Things are not always going to go your way, that’s just a fact of life. It’s how you handle yourself and get back up that shows what kind of person you are.
In the famous words of Chumbawamba, “I get knocked down, but I get up again. You ain’t never gonna keep me down.”
