I believe work is the source of happiness. Happiness comes to you when you see the fruits of your work.

I remember feeling really happy after finishing up a program that I had been working on for a long time. Just seeing it work so perfectly gave me an incredible sense of satisfaction. It was far better from the satisfaction/pleasure I got from doing things like watching TV/movies, going on dates, eating at nice restaurants, etc.

Developing the program was definitely not play either. It involved things (like fixing bugs, coming up with algorithms) for which I had to expend a considerable amount of intellectual energy. It was work, but it was work worth working on.
