I don't pay enough attention to know, honestly. I know people who invest their own money and put a fair bit of time into it; they seem to survive just fine. But they're either angel investors or long-term value investors, and those don't seem like what you're looking for.

If you just want a hobby, have you considered just doing it as a game? You don't actually have to execute the trades.

If you want to do real money, you might consider whether you think you are prone to a gambling addiction. I've seen some very smart people think they had a great system for beating the market get hooked on the gambling aspect and lose a lot of money. One of them ended up mishandling other people's money; they were lucky to stay out of jail.
