I feel like I have just climbed Mount Everest. As a child with dyslexia, I was unable to coordinate the movement of my hands and feet — upper and lower body. Suddenly, after I started lesson 15 when I used “The McClintock Walking Experiment,” I found I could clap my hands and pat my feet at the same time. At age 72, I feel like a new woman! I am up at 6:30 a.m. and by 7:30, I’m at the piano. I come back and play some more on my lunch hour and again at 4:30, when I finish work. How can I ever thank you for adding this joy to my life?
