Can someone make a long-term career at online poker?

I started playing September '03 for real money when I won $70, then $100 at two different freeroll tourneys.

Since then, with bonuses, I've managed to build my bankroll up to $16,028 without a single deposit.

By playing tight aggressive with premium hands in hold 'em limit games, I started at .50/1, and now play mostly $2/$4 games - 4 tables at a time.

I don't think these sites are rigged, because if you're a good player (patient and disciplined) in the long run you will win. And if I ever feel uncomfortable at a site, I stop playing there and go where the money is. Also, if you know which hands to play, in which position and know when to give up you hand, I think the odds remain in your favor and can't imagine that I've won consistently because I am "lucky."

I'd say about half of my money came from bonuses though... and I'd recommend people try other sites for this reason.
