I do not consider my time when I play Poker, for me it is not a form of work, it is a pastime I enjoy and when I am in the mood I can play for hours, Playing for fun makes the game much more than simply making a living from it.
Why do people go drinking, fishing, or sun bathing on a beach, it is not because they can make money from it, they do it because they enjoy it, so time has no meaning, I am lucky in the fact that now I am retired, I do not need to use my time making a living, so time has no value other than the fact I use it for my personal enjoyment, and gratification.
Make the best use of your free-time, doing what you enjoy most, for me that is playing Poker!
When the fun Stops, STOP!
