I gave it a shot at just over $100/day @ 6 hour days 6 months after learning that a flush beats a straight.

I was 19 at the time though so that's more then any job I'd be working + the benefits are priceless...always have a plan B and C though that's why i'm part timing school...and if I'm not making around 100k+/yr by the time I'm 22 I'll be dropping it.

but yeah...if you're young enough with no dependants definitly give it a shot if you love the game and are a consistent winner, never be satisfied by how much you're making and how good your game is though.
