The only people that succeed in trading are skillful and professional trader...
An amateur becomes skillful with regular practice. You make mistakes, learn from them and keep trading till you make very few mistakes (if ever) then you will be called a professional.
That's true because we all started from newbie but because of the fact that we want to learn we work our way to learn trading..And for me, it's important that along the way you have to make sure that you correct your errors and not doing it again and again. By adjusting we are making ourselves matured in trading which could give us a good chance of success.
