But how about the surroundings? if you have a group of friends who regularly gambles it's not possible to be a gambler too.
It will need a strong mind to prevent us from becoming a gambler. That is hard because the tempting to play will always there especially our friends still asking us to play with them. And it is why we need to know how to reject if they ask to join in the games. Perhaps we can follow them to play together in one time in a week but don't follow them every day because we know that the chance to become addicted will wide open.
Its our decision that will matter and no matter who their are if you know what is right you will do it. Beside, those are just your friends and not even your family so if they are true with your friendship they will not force you to gamble and they will respect your decision. The danger in addiction can be avoided in early stage, just control yourself.
