Something that made my week this week was a parent sending me a note saying "Best piano recital ever!" She signed up her son to have a motivation fund of $50 toward his hover board if he can do his homework and piano lessons every day right after school for 3 months. He has been nailing it and because of the now habitual piano practice, he is doing better than ever at the piano. Now, how do I maximize the value of this testimonial? Written testimonial? Do a video of me on YouTube so people hear my excitement? Get her to do a video review? All of the above?
