I trade for a living. Period.
People I talk too, do not really understand what that means. Do you make money in the market? Do you have a tip? No... First of all, it is a probability game and with that said, most people are already lost. How many people do you know, really understand probability? If you have a system that makes money 75% of the time, you can have two (three? four?) losses in a row any day. But the one that does make money, makes it worth it.
