When I started gambling my mindset is solely about winning some cash to better my life but the more I gamble, the more that idea shifts. The money no longer satisfies my initial goal but the idea of winning does.

But even with those ideals in play, why would a millionaire start gambling in the first place? 

so why would a rich athlete or politician become so addictive to gambling?

I think socialization+joy+drinking+gambling is satisfaction to them. What do you think?
