A little practice will convince us that we can, by controlling our imagination, reshape our future in harmony with our desire. Desire is the mainspring of action. We could not move a single finger unless we had a desire to move it. No matter what we do, we follow the desire which at the moment dominates our minds. When we break a habit, our desire to break it is greater than our desire to continue in the habit. The desires which impel us to action are those that hold our attention. A desire is but an awareness of something we lack or need to make our life more enjoyable.
