William Shakespeare (baptized 26 April 1564; died 23 April 1616)was an English poet and playwright, widely regarded as the greatest writer in the English language and the world’s pre-eminent dramatist. He is often called England’s national poet and the “Bard of Avon”. His surviving works, including some collaborations, consist of about 38 plays, 154 sonnets, two long narrative poems, and several other poems. His plays have been translated into every major living language and are performed more often than those of any other playwright.

Of all knowledge, the wise and good seek most to know themselves.

Thou sleep’st: awake, and see thyself.

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

This above all: to thine own self be true,
And it must follow, as the night the day,
Thou canst not then be false to any man.

I know myself now, and I feel within me A peace above all earthly dignities,
A still and quiet conscience.
