I think the keyword here is "psychological". If you train yourself to control your mental state you can suffer all sorts of physical afflictions but psychologically you can still be as happy as ever.

I used to think that balance was the key, but after some consideration I'm undecided. If spending all your energy on training yourself to be happy actually makes you happy despite your physical well-being, why would you need balance?

My friend had a good quote: "if you're trying to be happy, you've already lost." Happiness comes from satisfaction with the present moment.
