Laughter is a tranquiliser with no side effects. Stars can't shine without darkness.

Happiness can exist only in acceptance.

Don't let yesterday take up too much of today.

Happiness depends upon ourselves.

Be faithful to that which exists within yourself.

The things we love destroy us every time.
