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.
For most people, gambling is just for fun. Most of us cannot live on gambling as too much skill is required to gamble professionally. There are not many reports about living on gambling only.
