Life is a series of collisions with the future; it is not the sum of what we have been, but what we yearn to be.
Jose Ortega y Gasset
It is not length of life, but depth of life.
Ralph Waldo Emerson
In three words I can sum up everything I’ve learned about life: it goes on.
Robert Frost
Don’t go around saying the world owes you a living. The world owes you nothing. It was here first.
Mark Twain
Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment.
Buddha
Every man dies. Not every man really lives.
William Wallace
