Things we must do to stop gambling according to experts:

Greed is the main problem. Most gambling addicts think if they play long enough some day they will get rich but of course that's not true. It is because the games are designed to make you poor in the long run. These people will never understand this fact so they keep playing and getting poorer and poorer.

The moment they identify this problem and understand it fully, one question remains to be answered.

"Do you want to get poor or not?"

Yes > keep playing.
No > stop playing.
