This above all to thine self be true意思

"This above all to thine own self be true" is a quotation from Shakespeare's play "Hamlet." The full quote is as follows:

"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."

This quote is spoken by Polonius, a character in the play, and is advice that he gives to his son, Laertes, before Laertes leaves for Paris. The advice is that Laertes should be true to himself above all else, and that if he does this, he will not be able to be false to anyone else.

The quote is often interpreted as meaning that it is important to be true to oneself and to one's own values and beliefs. This is a theme that is present in many of Shakespeare's works, and it is a theme that is still relevant today.
