If you have control over how much you can spend out of the money you have and the ones which are disposable, that's a good one, but you also need to study and limit the amount of time which you also spend on the board because you can have an amount limit to spend from your budget, but if you are lucky and get some winnings, that limit might never get finished, which is where time control comes in; if not, you will end up losing that money you manage to win.
Limiting amount we can spend on gambling is important so that we don't have to use all the bankroll to gamble for nothing. I gamble with the amount I know I can afford to lose and this is the pattern we ought to use and gamble.
Using small stake to bet is better than using big stake and later losing the money for nothing.
