"Whenever I face a hard decision or a risky situation in life (personally or professionally), all my thinking, all my analysis, all my planning can be boiled down to four simple questions: 1. What is the best thing that can happen if I do this? 2. What is the worst thing that can happen if I do this? 3. What is the best thing that can happen if I don't do it? 4. What is the worst thing that can happen if I don't do it?"
