And you are right, do it if things working well to avoid hurting too much with your deposit balance..
And I know that things in each one of us have a way of solving things, I would say that I can apply emotional control but not in the middle of a game in a casino , for me what works is being able to control my money, if I control my money and I have the Discipline to be able to do it, it prevents me from spending more money, in the end I think that is the idea, not to spend unnecessarily.
