This means that we only need to have a gambling budget, set limits, be disciplined, be able to accept defeat and win, have a grateful nature, have wisdom in making decisions, not prioritizing emotions but prioritizing logic are requirements to be able to gamble responsibly and be much calmer, very few people can be responsible for themselves in a good self-control mechanism, here the power of reason and knowledge is tested, not everyone can do it even though they are smart, pleasure is born from things that can be accepted by us, indirectly we already know for every choice you make, if you don't win you lose, and that's it.
This is exactly what is needed, it is a mental exercise and above all it takes a lot of strength of character. If you set a limit or a budget or whatever you want, the important thing, what requires a strong character, is to maintain it without exaggerating and without going outside the limits of the budget you have set for yourself.
