And for me that's living a less self-centered life.
I am happy when what I do with my life enriches the lives of others. But being transactional about this ruins the game. It is, among other things, the opposite of zero-sum. Do the thing for the exuberant joy of the thing itself, don't take yourself too seriously or try to carry too much weight, and act in the trust that, but do not demand as payment that this will lead to a happier place.
