Always carry a notebook. Write everything down. When you have an idea, write it down. When you meet someone new, write down everything you know about them. That way you will know how much time they are worth. When you hear something interesting, write it down. Writing it down will make you act upon it. If you don’t write it down, you will forget it. That is a million dollar lesson they don’t teach you in business school. – Aristotle Onassis
