It is greed you should be scared of. Addiction is triggered by the greed.
Emotions, I think is the correct term. Greed is a factor emotion (but as for all, it seems to be the most recognizable of all). Addiction is triggered by the action of the user, Greed will only take effect once the the user's emotions triggers.
Addiction in gambling is different.
Well, I'd agree at some point. But addiction in general is can still ruin one's life. I.e. Addiction in alcohol, drugs, and etc. those type of addiction is has no difference in affecting one's life like gambling. TBH, too much is too much and for me any type of addiction can really make one's life miserable at some point.
It's easier said that done, mate.
On point!
The first thing that a addict should do is that admit to himself that he has a condition. Otherwise, if he is on denial, no one can help him. Yes there should be supports group like families, friends and medical help. But if refuse and admit that he is an addict then there's nothing we can do about it.
In addition to this accepting, the fact is quite hard for those who are experiencing, and it's really a challenge.
If he was able to hurdle this first step then I'm sure it will help him a lot and he/she can channel the mindsets to different thing to get ride of his addiction, it will be very hard and difficult in the beginning, but if he wanted to quit for good, then absolutely he can do it.
A lot of people, do fail on the first step and lose his/her battle. Despite all the help they receive.
