Divide your life into sections that you desire to have vision for. Be sure you have at least three categories
Write your desires
Write every desire you can think of for each category of your life. There is nothing too big or too small.
Make sure they are "you" focused
Ensure that your desires are things you are in control of. Specifically speaking you can't desire things for other people because you have no control of other people. *Insert my favorite phrase* Worry about your own self. These are dreams, aspirations and ambitions you desire for YOU!
