The best made plans seldom work just as you planned. In fact the more detailed your plans the less likely things will turn out as you planned them to.
Since things are not likely to workout just as you planned them it’s more important to know your plan ‘B’…and ‘C’ for that matter. If this doesn’t work…then this…or that.
Prospects will go with the competition, people won’t meet deadlines, prices will go up, you’ll get sick, and you’re sure to have technical problems.
Be sure to plan into your master plan that it won’t work as you planned.
