Quote from alfonso:
It is a true goal.
It's a modest goal, yes, but we all have to start somewhere.
Others have mentioned it, and I think it warrants repeating, that beginning trading because you want that sexy HDTV is very close to saying you're going to make the market pay for it.
I think what you actually have are, or should be, two separate goals: get HDTV and get good at trading.
I really think that's a better way of seeing it than something like "I'm gonna trade because I want a new TV". I know that's the way we usually go about other things in life, like "I wanna nice holiday this year, so I'm gonna put in some more hours at the office", but I think it can be pretty dangerous when applied to trading.
I think it's safe to say that most people start trading because of the "dream life" (cars, trips, houses, [insert fantasy] etc) they think trading will bring, but somewhere along the road from there to successful trading something changes, and the goal becomes simply "to trade better", ie just trading for trading's sake.
In any case, I wish you all the best with your endeavor; it'll be an interesting experience, I'm sure.
