You've read the quotes:
“A goal without a plan is just a wish.”
― Antoine de Saint-Exupéry
“If you don't know where you are going,
you'll end up someplace else.”
― Yogi Berra
“Someone's sitting in the shade today because someone planted a tree a long time ago.”
― Warren Buffett
Yet so few of us plan adequately. And of those of us that do, many don’t execute effectively. Over the years, I have witnessed the power of a well-executed plan many times. Unfortunately, I have also seen the results of either a poorly executed plan or no plan at all. Not pretty. There is always a detailed explanation as to what went wrong. The marketplace, competition, not enough marketing support. The list goes on and on.
