Many people say they can’t come up with a life vision.
Those same people, on the other hand, can tell you things they want in their lives. They have travel destinations they want to go to, they have possessions they want to own. There have many glimpses into what their life vision is.
My advice is to simply keep a list of all the things you can think of that you want to have or want to do. Revisit this list once a week for 6 months and keep adding little things you want to have or want to do in your life. After six months group the list by the different life areas. The life areas are career, financial, lifestyle, love, social, family, fun, health, lifelong learning, and personal growth.
The sum total of the things you want to have and want to do is your vision. That is the life you want to work towards creating. It is that simple.
