“Everyone wants to feel like a winner. It’s tempting to pat ourselves on the back for making a winning trade, but it’s essential to face the facts: Many times a winning trade is a combination of an astute insight AND being at the right place at the right time. In other words, external circumstances such as plain good luck make you a winner.

When you put too much of your ego on the line with your money, you may feel great when you win, but on the other hand, you may feel discouraged when you lose. When you allow your ego to enter your trading, you put subtle pressure on yourself to succeed. This added pressure could compel you to make dumb mistakes like holding on to losing trades to avoid hurting your ego. It’s better in the end to take a professional approach to trading marked by objectivity and rationality. Sure, it is necessary to have a passion for what you do, but it is not necessary to get a swelled head.”

Indeed, one of the most important things you can learn is to keep your ego under firm control so that you’re never in the position of having to protect it when you’re wrong. Doing so is usually a costly mistake, even though we all let our own egos (and yes, that includes me) get to the best of us sometimes.
