I have to say I don't mind getting older.
The basic rule of free enterprise: You must give in order to get.
As I get, I give. Giving as you get is critical. It has everything to do with being happy for yourself, and making others happy is the cause of making yourself happy, and it's the cycle of giving and getting.
As soon as you stop wanting something you get it. I've found that to be absolutely axiomatic.
Perhaps all human interaction is about wanting and getting.
Wanting is the beginning of getting.
Getting and spending, we lay waste our powers.
