I do not think that gambling is a bad thing, as the game a person must understand himself when he needs to stop. I have been playing in casinos for a long time and I don't consider casinos as a source of income, it's just a form of entertainment for me.
I do not have much free time, so now I usually read specific literature, that is helpful for me. Now I am reading "Paul Langer - Black Book of Forex trading", as it helps to understand all aspects of trading Forex in the USA. But I am looking forward to the time, I can read my favourite Tolkien.
