Waste

When I play poker online, I spend way too much time fuming about misfortune. Bad beats don't keep me from winning though; bad decisions do. Any given decision in a limit hold'em probably is worth a fraction of a big bet, so its easy to overlook a $0.90 mistake when you just lost a $104 pot to some idiot who called you to the river with his pocket 3s. But those little mistakes add up and that's what gets your winrate from 0.5bb/100 to 2.0 bb/100.
