In Norman Doidge's book, The Brain's Way of Healing, he talks about visualization. When I'm treating clients, I believe it is important to think good thoughts and speak uplifting words. It was interesting to read that when we visualize, we activate several brain areas. This activation can create new networks of neurons firing together. This creates neural plasticity. Believe me, I know: 5 years ago I didn't think I would be able to practice again. My brain was paralyzed by negative thoughts. Can you train your brain to think good thoughts? Absolutely! Does it get easier the more you do it? Absolutely!
