Agreed! Discipline, along with smart risk management, creates a strong foundation for success. Emotions can ruin a person's judgment. But if a beautiful discipline is added to emotions, then discipline not only controls emotions but also snatches the desired victory from people. Then we can enjoy our victory with peace of mind.
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.
