Getting real
The really cool thing about Lady Variance though is, she doesn't remember whether the past was positive or negative. The past is the past and the $ he won is in the bag. The player however, does remember the past. In my earlier days, when I experienced a nice positive swing, I subsequently slacked off and didn't do things as perfect as should have been done. This is usually when Lady Variance would soon show her negative side. Then when I was having a negative swing, I was tight as a tic with my game and everything soon went pos again.
I think the main thing to focus on now is your math. Did you over-cook the math of your bank-role? Reexamine your game and your math and don't let your pos variance in the past give you a false sense of security. In other words: DON'T GO AND BLOW IT.
The moral of the story is; always stay tight as a tic with your math and your entire game and never let your guard down.
