You're only as young as the last time you changed your mind.

Hope springs eternal in the human breast.

We can know only that we know nothing. And that is the highest degree of human wisdom.

Happiness never decreases by being shared.

If you’re lucky enough to find a way of life you love, you have to find the courage to live it.

In three words, I can sum up everything I’ve learned about life: It goes on.

The important thing is not to stop questioning. Curiosity has its own reason for existence.

You are your best thing.

Life engenders life. Energy creates energy. It is by spending oneself that one becomes rich.

The only safe thing is to take a chance.

My turn shall also come: I sense the spreading of a wing.

I still believe, in spite of everything, that people are truly good at heart.
