My grandfather bet on the horses every day. He had 2 rules that he stuck to - most people can't stick to them like he did, but it allowed him a source of entertainment without short changing his family obligations. Rule #1 - NEVER EVER Bet with money you can not throw away -literally! If you can afford to put that $2 or $4 or whatever the amount; to place it in the garbage can, then you can not afford to lay down that bet. There is no such thing as if I bet this $2 by buying a lottery ticket or whatever, when I win, I will have made that $2 grow. Doesn't happen! Rule#2, never mix you money. He always had in mind, how much he was going to bet that day. That money went in one pocket, everytime he would win, he would place that money in a different pocket and that is exactly where that money stayed. Once you start betting back your winnigs, pretty soon, you end up like that young lady who visited the carnival and came home $200 lightier. I have tested both of these theories and they work well, for the non-addictive. Gambling can be as caustic has alcholism or drug addiction.
