Changing is not impossible.
Changing s always a choice we have.
Changes can easily be done specially for things that are only causing bad things in our life just like gambling. If we really love ourselves and people around us who care for us we can easily go away in excessive gambling and do things that will benefit you and other people around you.
you said benefits , gambling has benefits too . it gives fun and money that can make you happy and others too but too much gambling is not healthy anymore and will always lead to being busted . change is not a choice that we look for if we are on the addicted state but instead we will keep playing and playing even if we know that we are not already normal . this is a scary state once you are on it . we need to be more spiritual and ask help for god , this is what i do before and luckily i slowly recovered .
