… is your misunderstanding of the concept of planning.
Whenever you make a plan that eventually doesn’t work, and you blame the plan, or you blame yourself for making that plan, or you dismiss planning altogether, you are acting from a position of helplessness. And helplessness never… helps.
It is solely your responsibility to make a realistic plan and follow it to completion. So leave the plan alone, it is not guilty. It is a tool. Like any tool, it hasn’t got any power of its own. Like a hammer won’t nail two pieces of wood by itself, your plan won’t work, if you don’t use it properly.
Good planning skills have nothing to do with plans, they are all about you – your evaluation skills, your fears, your motivations, your focus, your drive. Everyone fails to plan effectively from time to time – because planning is orientative. Plans, by definition, are made to change, adjust to the practice they’re applied to and the factors involved.
This only means you have to continuously overhaul your plans, and, most important, do some inner work, never forgetting who’s in charge of your life.
