It is a fact, according to what I have applied throughout my life as a player, I determined that controlling our money is the best thing that can be done, because I control emotions and everything, so there is no better combination than money management and discipline, what happens is that sometimes discipline fails, because our mind makes us think that we can continue winning or risking more and that is when we make mistakes.
Controlling our emotions is making us able to control our money as well.
Because when our emotions have been mixed up, our control to our money is also losing. So if someone is good at one, it's possible to be good at both.
And then with having such qualities, makes a better and a responsible gambler.
