Gambling as an income?

HI, I have a friend who plays online poker for a living. he makes a good salary at it but he is very skilled. I think he gets bored of it though, same thing everyday, no face to face interaction with people etc. My experience of online gambling is that it is dangerous!! I got myself into trouble with it and had to install a gambling block on my computer. Its really addictive. I know that sounds stupid as everyone knows gambling is addicitive but if you arent careful it becomes all consumming! I consider myself to be a normal person with a good level of intelligence but i found myself pouring money away week after week into online casinos. Let me tell you THE HOUSE ALWAYS WINS!! apart from winning the lottery or turning to a life of crime the only way to make money is to work damn hard at something and be good at it!! I'm keeping my fingers crossed for a lottery win, i need it to clear my gambling debts!! x
