any of you do this? not that I have a particular interest in it, I just keep seeing that damned commercial for Ameritrade. I know nothing about buying, selling or trading of this sort so I was wondering if some of you do it. if so, are you relatively successful at it? how does one learn about investing in your own future? I don't think i'm willing to gamble with my 401k but i'd like to have a better sense of where my money goes.
