William Shakespeare

The course of true love never did run smooth.

Make use of time, let not advantage slip.

It is not in the stars to hold our destiny but in ourselves.

A friend is one that knows you as you are, understands where you have been, accepts what you have become, and still, gently allows you to grow.

A fool thinks himself to be wise, but a wise man knows himself to be a fool.

The fool doth think he is wise, but the wise man knows himself to be a fool.
