I have the same thoughts as you. I never count the money that I have won or lost in gambling. Every day is a new gambling day for me and if I keep remembering the previous lost, it will make me to try to chase the lost money, which is bad for my gambling habit.
We have to think very positive way, otherwise, we have to be very negative and start loosing more in gambling. In my case, gambling is not a money-making machine and we cannot win every time in gambling, an ODD chance is there and we have to consider those in order to move forward. When we are continuously gambling it is impossible to calculate profits and loss.
