Basically you gamble only when bored so most provably this addiction will not gonna happen if you have a life outside and it will just occur if you are staying at home facing your computer for long hours so to avoid this its really better to anyone to shutdown all things which can give you an access to your computer and never install any casino app on your phone so that you will not get tempted to play wherever you are.
I have a friend that became addicted on gambling even though we are very active on sports and socializing. I believe the bored feeling is not the main reason for addiction but only one of the contributing factor on it. Having a source of money to gamble and experiencing the feeling of winning is what makes people keeps coming back and addicted to gamble.
My friend keeps skipping on our hangout and focuses on gambling even though we have a lot of things to do. Addicted person dont care anymore about socializing if they still have money to play.
