To make a new beginning, in other words, people need the Four P’s: the purpose, a picture, the plan, and a part to play. For any particular individual, one or sometimes two of these P’s will predominate. Your own path into the future probably emphasizes one of these Four P’s—and minimizes or even omits others. As a result, you will tend to stress your own preference(s) when you communicate with others. You may naturally assume that others approach beginnings the way you do, but that isn’t necessarily so. People are really different—they aren’t just “defective” versions of yourself. So it is important to remember to cover all four of these bases—purpose, picture, plan, and part—when you talk about the new beginning you’re trying to help people make.
