As a new trader, be sure that you will lose money a lot depending on your risk appetite. In the beginning, you may win big and think it is easy, that you are smart or it is not as bad as people claim. But, then you will lose it all shortly afterwards. That will bring you to your sense. Just, that you will feel very disappointed or paranoiac You will think people are cheating at the game to the point you will want to give up.

But, if you are careful in the beginning, you will avoid all these pitfallls. But, that is impossible as a beginner to understand it. You will read about money management, entry exits and all the blah blah.
But, until you have been tested to your cores, you will not understand the power of emotion in trading. So good luck
