Did he write Happiness is a Choice? I admit I haven't read his works, and my judgements are based only on the statements I've seen, keeping in mind I may not be getting the full understanding. I do not believe happiness is a choice, if he means it directly. I can't look at my life the way I look at it and be happy. However, if he means indirectly, meaning, you can choose the way you look at things, then, yes, I'd agree. I can't just tell myself, "Be happy," and POOF! I'm happy, but I can see things in a different way (sometimes somebody has to show you a different way first, because we can't always see it on our own), and that way of looking at things may make me happy.

And, of course, the choices you make in life can lead to happiness.
