Your Biggest Enemy is emotion disguised as investing.

Your biggest enemy in the market isn't volatility. It isn't the next crash. It isn't even a bad stock. Sometimes, it's you. You buy because everyone else is buying. You hold because you don't want to admit you're wrong. You sell because the market scares you. Then you watch the stock recover without you. And suddenly, you buy again — at a higher price. That's not a strategy. That's emotion disguised as investing. The market doesn't know your entry price. It doesn't care about your conviction. It doesn't owe you a recovery. The moment you understand this, you stop trying to make the market prove you right. You start asking a better question: “What should I do with the information I have today?” That's where rational investing begins.
