A lot of people do not go no where near gambling, simply because they try to steer clear from becoming addicted, but personally I think its a great money earner.
I personally began playing when I was about 20 years old and to be truthful I lost quite a bit of my cash when I first began, I believe it was because I was a bit naïve and thought I was the best player. But I decided to do something about it so I read manuals both online and offline, I was getting great at the game.
My speciality was poker, I was basically the king of bluff and no one could beat me, I regularly visited my casino and was earning a bit of extra pocket money. It was not until I got my first internet connection that I got obsessed with something called Rakeback, but it was a lot different online and a whole new ball game, things were a lot harder because you could not see who you were playing against and the whole purpose of poker is being able to tell when someone is bluffing. I again lost a bit of money to begin with but then I started to master the art.
The online audience is much bigger so that meant the jackpots were bigger, and I started to win quite a few so it was all adding up. Within a few years I managed to buy myself everything I needed, so no one can ever tell me that gambling is no good.
