Ayn Rand

I swear, by my life and my love of it, that I will never live for the sake of another man, nor ask another man to live for mine.

To say 'I love you' one must first be able to say the 'I.'

Achievement of your happiness is the only moral purpose of your life, and that happiness, not pain or mindless self-indulgence, is the proof of your moral integrity, since it is the proof and the result of your loyalty to the achievement of your values.

A creative man is motivated by the desire to achieve, not by the desire to beat others.
