Learn to minimize your fear and to embrace disappointment as cheerfully and positively as possible. Count on people to fail you. Plan on people never coming through. You are going to have to fight your way through all on your own. One thing you can count on is people not showing up when you need them. Don't look at people's unreliability pessimistically, just vow to never be like them yourself. If you build people's failures into your success strategy, you will not be caught off guard by surprises. And, when and if someone ever comes through, you can rejoice in the rare blessing of that event! Be continually surprised by people, rather than being continually let down.
