Somewhere along the way in your LIFE, you were programmed to do that. It may have been through an emotionally charged association or as simple as a trigger caused by a deep seated Habit Pattern that you have now forgotten existed.
Imagine for a moment if you could control what you do, by allowing your subconscious to work automatically to enable your outcomes by programming your own mind, making your life so much easier.
Would that be valuable?
You better believe it would. This is what high achieving individuals do on a daily basis. They program themselves for performance and their subconscious does the rest of the work.
