EVERYBODY has a plan, an idea, a direction they know they want to head but then something hit them they weren't expecting and what happens??? Their world gets rocked, they get shook'd and they don't know what to do. Expect the worst, prepare for THAT, and be ready for it when it comes. Instead of telling yourself why a deal will close, tell yourself all the reasons why it WON'T. This way you can work around those reasons in your presentation and be ready for the objections when they come. Have a plan, but make sure you're preparing the RIGHT way, not just the easy way.
