For me it's simple, just spend the money that you are willing to lose, and for that you also have to have discipline because everything is based on the fact that we can generate ways to control ourselves, if there is the discipline for that then you can play calmly, in fact that is what is advised, otherwise I don't see what other way it can be done, there are some players who say they control their emotions but for me that is very difficult, but by controlling money all emotions are controlled, so for me it is better that way.
