Only a life lived for others is a life worthwhile.
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.
We make a living by what we get, but we make a life by what we give.
Life is a journey, not a destination.
Trust thyself: every heart vibrates to that iron string.
A man should learn to detect and watch that gleam of light which flashes across his mind from within, more than the lustre of the firmament of bards and sages. Yet he dismisses without notice his thought, because it is his. In every work of genius we recognize our own rejected thoughts: they come back to us with a certain alienated majesty.
