If you can control yourself in gambling it is easy to overcome all obstacles but some gamblers have no problem at the moment but are suspected to be addicted in the future, they can take some steps to control themselves. This includes setting limits on gambling. Apart from this determining the amount of money spent on gambling can also be a good step in this regard also the more time spent gambling the more money wasted. Set a budget before the game and stick to it great if there is a win but don't be disappointed if the luck doesn't continue.
Controlling ourselves when gambling is a very important thing to do so that we don't cause big losses to ourselves or others. Setting limits when gambling can protect our finances so that we don't take all the money we have to gamble and this really helps us not to become addicted to gambling. In my opinion, people who can control themselves in gambling certainly have a lot of experience in the field of gambling so they know when to do it and when to stop.
You can control yourself from the beginning as long as the expectations you have out of gambling are aligned with the reality, if a gambler that is just testing the waters for the first time thinks they can obtain massive profits with gambling then they are just setting themselves up for failure, since their beliefs will drive them to make bets that are too high expecting to get some profits in return, however if a new gambler took the time to read about the probabilities of the games, the different games and casinos they could be interested and they also read the TOS of the casinos they may like to use then that gambler has very low chances of spending more than what they planned.
