Yes, the course starts by laying out some of the basic concepts involved in the Three Minute Therapy approach. It defines certain key terms, such as Preferences, Demands, Self-Defeating Behaviors, and gives you ways to diagnose these in yourself. Then it gives illustrations of the Three Minute technique applied to specific problems and walks you through the approach step by step in a clear and simple way. It then encourages you to practice the Three Minute exercise on your own and make it a lifelong discipline. That's a key question and the answer involves the basic principle of learning.
Repetition is the royal road to learning.
When we repeat and reinforce an idea or a behavior, we tend to build pathways in our brain that makes it more a part of us. The practice of the Three Minute exercise serves this function. If you want to play some melodies on a guitar, you practice the guitar. If you want to speak French, you practice French. The Three Minute approach is based on the same learning principle.
