Nature arms each man with some faculty which enables him to do easily some feat impossible to any other, and thus makes him necessary to society. ... Society can never prosper, but must always be bankrupt, until every man does that which he was created to do.
Time rides with the old
At a great pace. As travellers on swift steeds
See the near landscape fly and flow behind them,
While the remoter fields and dim horizons
Go with them, and seem wheeling round to meet them,
So in old age things near us slip away,
And distant things go with us.
From time to time, little men will find fault with what you have done...but they will go down the stream like bubbles, they will vanish. But the work you have done will remain for the ages.
Remember this. Bear Bryant retired at age 69, and he died 28 days after he stopped coaching. If you don't have something, and a purpose in your life, you're gonna die.
