We are here to add what we can to life, not to get what we can from life.

There is just one life for each of us: our own.

There are three constants in life... change, choice and principles.

Life is but thought.

Don't go through life, grow through life.

Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less.

You will never be happy if you continue to search for what happiness consists of. You will never live if you are looking for the meaning of life.

The chief danger in life is that you may take too many precautions.

A chief event of life is the day in which we have encountered a mind that startled us.

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