Most successful companies, institutions and organizations have mission statements. Most individuals don't. As the Chief Executive Officer of your own life in the knowledge era, you need a laser like focus in your vision. You need a mission and a mission statement describing how you want to live, not just what you want to own; defining the person you want to become, not just the title you want to see on your door; outlining the knowledge you will receive, not just the degree you'll earn or your next promotion.

I began the process this way : "To be aware of the uniqueness of my associates, clients, friends and family, and to treat that uniqueness with loving concern. I was created to lead myself and others to understand win­win relationships and how to use them to improve the lives of all persons with whom I come into contact."

You, too, can frame your mission statement starting with your core values, working outward to your material desires and financial needs.

Who is responsible for designing a personal mission?

A) A Chief Executive Officer B) The family and friends
C) The Individual D)  The company
 
Answer & Explanation Answer: C) The Individual
