Star Wars Episode 2
The way to promote something in your own life is by focusing on it. This will cause it to grow in influence in your experience.
This is an expression of the "Law of Attraction" and is how all "good" (wanted) and "bad" (unwanted) things are brought into our experience.
All things grow under the influence of our attention and therefore it behooves us to focus on the things we desire to see happen if we wish to live a happy life.
