Well, the best tip for those who have never gambled - keep doing so.

You may be a person with strong will,
but when it comes to playing most of the people can't control themselves and it's not their fault, it is just human's brain chemistry.
I always say my friends that you go to casino to play, not to win.
is a big problem. There are a lot of gamble treatment centers, but I highly doubt that it is treatable.
