In the end, it's not the years in your life that count. It's the life in your years.
He who has a why to live for can bear almost any how.
The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.
It is not the length of life, but the depth.
Life has no meaning unless one lives it with a will, at least to the limit of one's will.
Hard work is a prison sentence only if it does not have meaning. Once it does, it becomes the kind of thing that makes you grab your wife around the waist and dance a jig.
Like the Bible said, man was born to trouble. Henrietta made the trouble worthwhile.
He who has a why to live can bear almost any how.
Life should be an aim unto itself, a purpose unto itself.
Happiness comes from between. It comes from getting the right relationships between yourself and others, yourself and your work, and yourself and something larger than yourself.
