"We think of comfort and luxury as requirements for happiness. The only thing a person really needs to be happy, is something to be enthusiastic about."
An old saying, but one that seems to be true, at least from what I've seen. I know a lot of people in a lot of different circumstances, and (for happiness) the only constant across the board is the happy ones have something that makes them excited when doing it, planning it or even just talking about it.
So hmm... around what age was I the happiest... I'd say the last decade and a half has been pretty sweet. I got into music! I've always liked singing, but with technology making so many things possible these days, it's a great time to be a music nerd.
