The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.
Isaac Asimov, scientist and writer (1920-1992 )
Tolerably early in life I discovered that one of the unpardonable sins, in the eyes of most people, is for a man to presume to go about unlabelled. The world regards such a person as the police do an unmuzzled dog, not under proper control.

There is nothing like returning to a place that remains unchanged to find the ways in which you yourself have altered.

There comes a time in a man's life when to get where he has to -- if there are no doors or windows -- he walks through a wall.
Bernard Malamud, novelist and short-story writer (1914-1986)
The days come and go like muffled and veiled figures sent from a distant friendly party, but they say nothing, and if we do not use the gifts they bring, they carry them as silently away.
Ralph Waldo Emerson, writer and philosopher (1803-1882 )
It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change.

If you wish to be loved, show more of your faults than your virtues.
