How planning bridges the gap between where we are and where we want to go? Explain in brief.

Planning involves thinking before doing. It anticipates future and decides the course of action to be taken.
It is the process which decides in advance the objectives to be achieved and formulates plans, policies and methods to achieve them. In this way we can say that, it bridges the gap between where we are and where we want to go.
