I started gambling at the Fort Erie race track as a kid. We would sell discarded racing forms and programs to newly arriving patrons. When we had $2 or $5 bucks we would stop and go in and bet on the races. we usually won and kept gambling the rest of the day. If we lost that first bet, back to selling programs. I have followed horse racing ever since and have made some money betting the races, mostly just enjoy the whole experience.
I look at casino's as a form of entertainment. I'll take $100 to gamble with, if I break even or come close I look at it as a win, I had hours of fun at very little expense. If I lose the whole $100 (which hardly ever happens) it was an evening of fun.
