Thoughts--what product of the mind doesn't include thoughts? With your thoughts you create the world in which you live; be it good or bad and so you would do well to get a hold of them. A focus on your thoughts will most likely be part of your work.
If you create much of your world in your mind through thought, you then make those possibilities real with your behavior. What you choose to do; what you refuse to do when with all your heart you want to do it -- that's the interest in behavior. How it eludes you and how it betrays you. Knowing how to motivate, redirect and create in the midst of your life will be a topic for coaching.
Avoidance--the opposite of acceptance is hardwired into you; and works well when avoiding things outside of yourself (from the rush of oncoming traffic to the hot breath of a chasing bear). It only becomes a problem when what you're avoiding is inside you--like unpleasant thoughts, feelings, memories, or body sensations. Attempting to avoid these creates the opposite and so this paradox underlies all you do.
