Happiness Is Only Real When Shared

This quote is from one of the last scenes of the film Into The Wild; If you haven't seen it before, you should definitely put it on your list. The soundtrack is great too!

Happiness is more than just being happy with yourself, as an individual. True happiness is only real when shared.

What are your thoughts on this? When a moment of happiness does occur, do you find that you look for someone to share it with?
