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 made the decision to become a much better player, so I practiced and practiced and eventually became a very good player.
My speciality was poker, I was basically the king of bluff and no one could defeat me, I regularly went to my casino and was earning a bit of extra pocket cash. 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. In the begin I did lose a bit, what I now call an investment because in the end I started getting really good.
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.
