have your specific entry area, profit target price, and stop-loss price all determined in advance before you pull the trigger.
I like to be 100% sure of my decision making. And when I exit a losing trade, I can't help but look back and see if I could have held longer. I also think this is a bad idea because it could affect me psycologicly. But then again I also think it could be a good idea because I could learn from it. What do you do after a losing trade?
Throw a screen through the room and cursing! LMAO!

Analyzing each individual trade is useless in the context of 50 or 100 trades. It means nothing. UNLESS you have one of those individual trades that ate your entire account, and that is a big risk management concern (and psychological).
Only by reviewing your trades you realize that you may have made a mistake. That is what a trading journal is for. Repeat the same mistake multiple times over the course of a year and it is not minimal! If you have say 20-30 trades that you could have avoided or handled differently, your bottom line is affected! Even at 2% risk per trade, you lose 5 trades and now, you are down 10% of your account value! Lose more, the bite goes even higher!
Reduce your mistakes, you improve your performance and increase your profits!
