Even when I was playing for good money and winning, the enjoyment factor was my measure of when to step away. I can sit there and play all day long and enjoy it. I have lost good money, but never cared because I was having fun. When it becomes close to an addiction, then I step away. If I am mad or frustrated, I step away. You can win money back, but it is never a good thing if you are sitting there feeling like there is no fun. The stress of a call is exciting to me. I have won quite a bit because of a river and lost some as well. Money is money. There are always ways to make more. Losing your cool because of a hand means your time is up if this is changing you.
