If you are good and patient, then yes you can do alright.
Reason i say patient, is that a few years ago after a monster 9 hours playing and about 4am in the morning I stupidly called allin when I was 3rd place chip leader out of 11 people.
I had AA and the flop was AKJ. It turns out I was up against KK and JJ. There was a K on the river and I lost all my chips to the chip leader.
Sadest thing was due to the length of time playing and my tiredness, I hadn;t realised we were down to 11 players. The top 10 players all got a $20,000 ticket plus accomdation and spending money to the WSOP in Las Vegas
Looking back I probably just could have kept folding and somebody would have been out before me.
Most I ever one in a game was $2500. Equally I could go nights without being up at all.
Overall I was always up but factor in I was playing 20 to 30 hours a week, minimum wage didn;t even come close! I was always hoping for that big win thoough and came close a few times.
