太对了，看看Peter Lynch如何说的

In this business, if you’re good, you’re right six times out of ten. You’re never going to be right nine times out of ten

Investing in stock market is a numbers game, you can not expect a perfect game, it does NOT exist. If you can not deal with loss, you should not start in the 1st place. You have to deal with failure, cut loss early, learn from it and move on.
