You need to develop your skills and analysis, once you become expert of different strategies in trading you won't fail in different situations. Learning stage isn't easy, patience and control of emotions is very important. Of course your self confidence always matter, everytime you deal with pressures and struggles in the midst of trading difficulties.
Yeah, I can't believe people think that just because they learned about TA they could become a good trader. This way you could potentially make small but sure tiny trades that would make you tiny profits here and there, or maybe even a bit bigger profits if you are ever lucky, but it is not going to be enough, that is not going to make you rich neither.
The reality is that if you end up trading into something that is profitable in the sense that you make 5-10% per trade and you think you can keep doing it, that will be rare and not constant, not sustainable, you can't make 5-10% profit per trade for many times a day for many days and years, if you were capable of doing that, you would have been world's richest person in a year even if you started with 100 dollars. So smarter decision would be to learn TA of course, but also try to see what the public opinion is and go in with courage to things you like as well.
