I'm on around 500K a year (after tax) - I am pretty happy - not 100% happy, and there are always small annoyances - injuries while training, bad service in a resturant, people who annoy me, an idiot taxi driver, not being able to fuck a chick you thought you would be able to get, etc, but these are all minor. But overall, I can say I am very happy. One thing to bear in mind for me is that I started with nothing. I appreciate money, as I worked for every cent. But its not the money itself, its what I can do with the money. I never have to worry about the cost of a meal, and can eat any place I want, drink anything I want, buy any clothes I want etc. If I want to travel, stay in nice places etc I can do it. I don't need to every worry about rent, where the next paycheck is coming from etc. So to that extent I think the money does help contrubute to my happiness. That can be compared to others who have a lot more, but perhaps always had it - rich parents, trust fund, etc. For them, having money is the norm, and whilst some of them are happy, quite a few don't seem to be too happy at all, have no direction in life, problems with the taxman, parents, the trustee, with drugs, etc.
