considering the fact that trading is highly profitable and responds majorly to knowledge and skills, this means its needs full attention and concentration consistently. i have noticed alot of new and upcoming trader gets carried away easily with little profits or loss. this makes many to quit or feel complascent becoming a good trader is like going to a school, you do all necessary things consistently without any distraction untill you succeed. this is one of the things that i feel is needed to incorporate into trading learning process and lifestyle.
Trading has different stages and until you reach the final stages which then your experience becomes a major factor behind your success, you haven't mastered the act of trading. Anyone can get lucky with their first trades so don't think because you got them right that you have mastered the act of trading. This kind of thought is want drives newbie into taking decision that are far beyond them like increase their risk side just because they had few trades correct.
It can be very frustrating at first when you want to become a trader, after few successful trades it'll feel like trading isn't for you as all you do will seems to not be working. Others would be profiting but when you try yours, you'll come out not successful. You don't have to quit, just need revisit your drawing board, probably taking some few weeks off the market might help.
Go back to learning, instead of quiting. If you do pass that very first frustrating stages then everything will begin to fall into place. Trading needs practice and consistency, discipline as well. All these helps to keep you focused.
