You know enough about the world to have a pretty good idea of what it will take to live the life you desire. Your brain can quickly give you an accurate picture of the person you need to become to create the change you desire. All you have to do is ask.
Once you have this answer, you can begin living as that person today. You don’t have to wait. You can think, act, and adopt the beliefs of a fit person, someone with a great social circle, or whatever type of person you are - the one in your dreams.
