Gambling is great fun...it's all about managing what you can risk and win.
I can't identify with either comment...I don't gamble for a living and I don't live to gamble but some times - weekends or a boring week night, when I'm on the road too, it's fun to just make some bets and see where things go. Betting on sports games is fun too, I do that a lot on American Football.
If you find gambling as fun then you are not making gambling for a living. Only some people who are finding gambling is profitable, they may turn into the living off gambling. I believe all the gamblers fall in these two category.
