Don't be too hard on yourself.

Trading is tough. Most everyone has lost money at some point and has had regrets. You may have made a bad entry or did not cut losses soon enough. When a good trade is made but maybe the stock went for even more profit, the temptation is to kick yourself for getting out too early (such as this trade). The word for today is: just relax. Of course, it is not perfect. Enjoy the moment. You won! I hope this helps you today.
