It is in the twenties that the actual momentum of life begins to slacken, and it is a simple soul indeed to whom as many things are as significant and meaningful at thirty as at ten years before. At thirty an organ-grinder is a more or less a moth eaten man who grinds an organ - and once he was an organ-grinder!

Young people are often asked, 'What do you want to be when you grow up?' and given advice about how to lead meaningful adult lives, but where's the encouragement to lead meaningful lives right now?
The animals of the world exist for their own reasons. They were not made for humans any more than black people were made for white, or women created for men.
Destiny ... a word which means more than we can find any definitions for. It is a word which can have no meaning in a mechanical universe: if that which is wound up must run down, what destiny is there in that?

Far better, surely, to use our short time here in living a meaningful life, enriched by our sense of connection with others and being of service to them.
