RANDOLPH’S RULES FOR SUCCESS Do at least 10% more than you are asked. Never, ever, to anybody present as fact opinions on things you don’t know. Takes great care and discipline. Be courteous and considerate always—up and down. Don’t knock, don’t complain—stick to constructive, serious criticism. Don’t be afraid to make decisions when you have the facts on which to make them. Quantify where possible. Be open-minded but skeptical. Be prompt.
