I always like to look on the optimistic side of life, but I am realistic enough to know that life is a complex matter.

Langston Hughes
Hold fast to dreams, for if dreams die, life is a broken winged bird that cannot fly.

Aristotle
Education is the best provision for the journey to old age.

Ernest Hemmingway
They wrote in the old days that it is sweet and fitting to die for one's country. But in modern war, there is nothing sweet nor fitting in your dying. You will die like a dog for no good reason.

R. Buckminster Fuller
Either war is obsolete or men are.

GreenPeace
Only when the last tree has died, the last river has been poisoned, the last fish been caught, men will realize that money can't be eaten.
