In fact, I think that is one of the main reasons why music is so integral in education — not because it rewires the brain in some mystical way, but because it teaches students perseverance and the value of delayed gratification. However, I am not convinced that “praise makes you weak.” (I’m not sure that’s what Joanne Lipman actually wants you to conclude that as well from her essay).
