i have to agree with fnord - if you're not willing to put some study into it, the going is going to be tough. there's no substitute for experience, but study gets you thinking about things outside of the "gotta make a decision right now" environment.

as to what to play, if big MTT's are what you like, play the $1, $3, $5 on poker stars. i would think that with just a little effort, you could at least get into the money often enough that you wouldn't lose money overall.
