My number 1 advice to anyone is to be prepared for HUGE flucuations in your bankroll/results. If you can not deal with that you have zero chance of success.
I am betting 30+ bets a nite and very very rarley do I get emotional about them but I do get a little excitied late in games that are close but the emotions leave minutes after the game is over.
IM, you have mentioned I believe lik 8 straight winning months, how much fluctuation to the negative could you possibly have experienced over that time?
I guess a + - unit description would be the best way to explain it.
