The only disability in life is a bad attitude.

A life spent making mistakes is not only more honorable, but more useful than a life spent doing nothing.

In three words I can sum up everything I've learned about life: it goes on.

Life is but thought.

I have a simple philosophy: Fill what's empty. Empty what's full. Scratch where it itches.

Only a life lived for others is a life worthwhile.

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

To live a pure unselfish life, one must count nothing as one's own in the midst of abundance.

To know nothing is the happiest life.

What is important in life is life, and not the result of life.
