i payed for my car playing 50nl on partypoker over 3 months. i don't pay my bills with poker but i do consistently add to my income as i only work part time. yet i still play the pokerstars and bcp freerolls, not for the $3, but just because i like to play poker, whether its for money or not. i still play for play money sometimes too.

as for people being rude and critical it actually helped my game when i started playing, i started to study poker a lot more. generally though its the worst players who are the critics and can't take a loss. if someone is really playing bad, why the hell would you want to point it out to them and possibly inspire them to change their game? adjust your game and exploit the bad players. and if you are a bad player, keep doing your thing
