The practices mentioned in the OP are really important. But I think if a gambler manages to control with the first three practices, then the fourth practice that is about alcohol and emotions won’t affect much. No one can really make money from gambling. Gambling is basically pure luck, and you can’t depend on it to earn money. Hence, only gamble for entertainment and not to earn cash. Now a wise man has said that you should split your work into smaller tasks and complete it one by one to finish the work. Similarly, in gambling, gamble in limits and targets. In this manner, tons of money will be saved.
