Geoff Kanofski is not a qualified psychologist. He was encumbered by symptoms of OCD, ADHD, and Tourette Syndrome. At age 33, he discovered how his disorders were functionally linked. This was the beginning of his understanding.
Geoff then began to overcome his OCD, which increased his understanding. At 35, he no longer suffered with severe OCD. He then began full-time study. Hard work and tutoring allowed him to complete two years of pre-tertiary study. Then disability concessions enabled him to complete an Undergraduate Degree in Psychology. Eight years of full-time study increased his personal understanding (of this functional link).
Then something happened that damaged Geoff's mind. He began to experience episodes of anger and sadness. Understanding how the functional link worked did not help his state of mind. His anger and sadness continued for a long time.
At 55, Geoff found a way to heal his mind. His journey enabled him to understand the difference between the brain and mind. His autobiography explains this in fine detail.
He finished writing this book when he was 64, and in his final chapter, he provides a hypothesis that is worthy of scientific research.
