“To thine own self be true and it must follow as the night the day, thou canst not then be false to any man.”

This is Polonius giving advise to his son Laertes.

Polonius is saying by this that we each need to be true to ourselves and live with integrity. I definitely think this is still true today. When we are being true to ourselves we will make better choices. Every choice we make has a consequence and if we live with integrity we will be making choices that will ultimately make us happier. I think that if you are living with integrity you wouldn’t ever want to be dishonest with another person because then you’re also being untrue to yourself as well.
