Trying to play longer and trying to win more will spark the desire of increasing your needs to keep on playing, be responsible for your actions and avoid getting that much engagement to avoid having addiction.
Therefore, gambling must be carried out responsibly by controlling oneself so that it does not continue to play until it becomes an addiction, because it always limits playing hours so that it is easily controlled or limits the budget for gambling, I am sure that gradually it will be easily overcome if you start learning to limit it and will help to avoid addiction.
So far I play with responsibility understanding every risk I face if I continue to play without knowing the time, limiting time and budget is the key to success I can play responsibly and in control, it is important for beginners so they don't become addicts should see a lot of experience from the players long time in this thread to be an important lesson for them.
Yes self control is a must in the world of gambling as we all know that every time we bet there's a greediness will come to our self that dictate us to bet more and more even though we are encountered many losses which pretty bad once we loss and bet more then loss again. So it's better to have self control for the sake of addiction because once we don't have self control then addiction can take over us easily.
