Always remember this: "Plan your trade and then trade your plan", there's no better thing than this if you want to start your trading career. If it's a wrong trade always program your mind that the next time you do it better.
There are too many factors you are on the opposite direction and one of it is your emotion, if you let your emotion on the frontline of your trade expect things a little bit messy. Trading is planning and you need to master it day by day, even professionals still learning everyday - it's a lifelong learning.
