According to the agile project management system, it is necessary to begin by setting the vision and scope of the project. Applying this to living a happy and fulfilled life is easy.
What is the vision of your life? What is your purpose? What, exactly, are you trying to accomplish? What is your life mission?
Pastor Craig Strickland, in Memphis, Tennessee occasionally would caution people regarding climbing the ladder of success too hastily. "Sometimes," he would say, "people spend their whole lives climbing the ladder of success only to, once at the top, realize their ladder was leaning against the wrong wall!"
So, what is the vision for your life? What is the mission you hope your life will accomplish? Over they years I have discussed life vision and mission frequently. Your visions must grow out of your fundamental understanding of your purpose as a person in the universe.
What is your "why behind all other whys"?
What do you believe gives meaning and direction to life? From that… and if you are to be ultimately content with life, from only that must come your life mission and vision.
It's hard work, but it is essential to figure all this out on the front end.
