How strong does a character need to be to set aside some amount of money on a weekly gamble?
What needs to happen to make it happen?
Does the great loss solidify our character?
What exactly does it mean to discipline yourself in gambling (in the narrow sense)?
Should we be disciplined in gambling, does it mean that we are better at gambling, or that we put less money at stake with more enjoyment, less fear, adrenaline, etc. ?
Me interested in answering the last question?
At first you have to think about fun, not about profit, forget this last one cause you won't gain profit on long term but on short term, possibly yes and there are a lot of people who were lucky ones and won much money.
Discipline in gambling helps by minimizing the loss and maximizing the joy of gambling. Look at casinos like services which offer you some games in exchange of some money and if you can get fun from these games, you have to pay some bucks for that. And in discipline I mean all of these things which I wrote + controlling your budget, you habits, doesn't matter whether it's pleasurable or not, mustn't affect your budget seriously.
