1. Devise a simple plan and stick to it. As a kid, Giuliani gained the edge on a neighborhood tough just by jabbing him in the head over and over again until he backed down.
2. Never lose your cool, no matter how rough the fight gets. Staying calm gives you the mental edge you need to go the distance and win.
3. Strike first. That reduces the number of times fighting will be necessary. Case study: When Giuliani learned that mob-run businesses were vying for contracts to clean up the World Trade Tower sites, it took him about two minutes to bar them from bidding on the business.
