determine the boundaries of how much you "will" lose per day and how much you will earn, for example, if you sit cash game with 20$ and after 1h your stack is 40$, sit out, and don't come back until tomorrow, so imaginary your profits will be 20$ per day X 25 monthly is 500$. And if after 1h u have 10$, again sit out and don't lose more then 10$ per day. You must control your self, coz you want to win milions on 1h, can't be done. So only thing you can do is control your self and losing money over + and - determined boundaries
