Two pieces of advice Polonius gave to his son before sending him off.
What are not to say what he is thinking and to think before he acts, he should hold onto his friends and not to be quick to make new friends, don't pick fights, but if you are in one, fight well, listen to many people, but talk to few, don't borrow or lend money, don't have too much fun, and dress well but not too nicely.
