OK. Here's the thing. I get ahead $200 and tell myself I'm gonna pocket $100 and play on the rest. That's fine if after playing the $100 I leave. But almost every time the casino action and the belief that maybe with "expert" strategy I can get more (greed) has a powerful influence on my resolve and many times wins the OTHER $100 I SAID I wasn't gonna touch. So if you're able to do what you say, that's fine-in my book. Then there's one more powerful influence to consider- how if affects your HABITS. Stopping when a winner and GOING HOME becomes a habit and believe it or not the wins become easier after a while. That, and the fact you have time to regain your common sense and savor the fun.
