So... When you're playing well (or at least winning), you play for as short a time as possible.... but when you're playing not so well (or at least losing), you stretch that out for as long as you can?

Do you think this is the best strategy to maximize your opportunities for good decisions at the tables?

I don't understand how "not paying rake" is a reason to stop playing when you're winning, or how "paying rake" is an incentive to keep playing when you're losing.
