Choice Theory states that all we do is behave, that almost all behavior is chosen, and that we are driven by our genes to satisfy five basic needs: survival, love and belonging, power, freedom and fun. In practice, the most important need is love and belonging, as closeness and connectedness with the people we care about is a requisite for satisfying all of the needs. Choice Theory (and the Seven Caring Habits) is offered to replace external control psychology (and the Seven Deadly Habits), the present psychology of almost all the people in the world. Unfortunately, this forcing, punishing psychology is destructive to relationships. When used in a relationship it will always destroy the ability of one or both to find satisfaction in that relationship, and will result in people becoming disconnected from those with whom they want to be connected. Disconnectedness is the source of almost all human problems, such as what is called mental illness, drug addiction, violence, crime, school failure, spousal and child abuse, to mention a few.

The Ten Axioms of Choice Theory
1.  The only person whose behavior we can control is our own.
2.  All we can give another person is information.
3.  All long-lasting psychological problems are relationship problems.
4.  The problem relationship is always part of our present life.
5.  What happened in the past has everything to do with what we are today, but we can only satisfy our basic needs right now and plan to continue satisfying them in the future.
6.  We can only satisfy our needs by satisfying the pictures in our Quality World.
7.  All we do is behave.
8.  All behavior is Total Behavior and is made up of four components: acting, thinking, feeling and physiology.
9.  All Total Behavior is chosen, but we only have direct control over the acting and thinking components. We can only control our feeling and physiology indirectly through how we choose to act and think.
10. All Total Behavior is designated by verbs and named by the part that is the most recognizable.
