I've come to the conclusion that a good portion of us suffer from ADHD. It is the hyperfocus that allows us to keep our mind always on the money, and allows us to come up with many different methods of extracting the money from a customer. It gives us a sense of urgency, and pushes us to our physical and mental limits. It allows us to absorb enormous amounts of information in a very limited time and apply it. Do you believe most successful entrepreneurs suffer from some form of mental disorder?
