What the 1% who takes all the money knows that you dont

I have started searching for information about foreign stocks and i discovered this site,english is not my mother language so i will make some mistakes,i have seen many muths in forums,and this one,so i wanted to say some things to new and medium traders, about the stock markets.
Maybe what i say will be a reason to stop trading (if you are smart) or try harder.
i dont like to write monologues so you can ask me what you want,i am not your teacher to answer guestions,but i dont like to write monologues either.
