William Shakespeare

All the world's a stage, and all the men and women merely players.

To be, or not to be, that is the question.

We know what we are, but know not what we may be.

Good night, good night! Parting is such sweet sorrow.

Brevity is the soul of wit.

Cowards die many times before their deaths; the valiant never taste of death but once.

The course of true love never did run smooth.
