Abraham Lincoln:

And in the end, it's not the years in your life that count. It's the life in your years.

Anais Nin:

Life is a process of becoming, a combination of states we have to go through. Where people fail is that they wish to elect a state and remain in it. This is a kind of death.

Captain Jean-Luc Picard:

Time is a companion that goes with us on a journey. It reminds us to cherish each moment, because it will never come again. What we leave behind is not as important as how we have lived.

played by Patrick Stewart, from the film "Star Trek: Generations"

Carl Sandburg:

Life is like an onion: You peel it off one layer at a time, and sometimes you weep.

Elbert Hubbard:

Do not take life too seriously. You will never get out of it alive.

Goethe:

A useless life is an early death.

HH the Dalai Lama:

What is the meaning of life? To be happy and useful.

Helen Keller:

Security is mostly a superstition. It does not exist in nature, nor do the children of men as a whole experience it. Avoiding danger is no safer in the long run than outright exposure. Life is either a daring adventure or nothing.
