Let me use an embarrassing example from my past. So how do I turn a negative into a positive?

I’m sometimes even tempted to make piano teaching mistakes on purpose (at least that’s the excuse I’ll use for my occasional blunders). In fact, where I once use to dry-heave upon the discovery of my mistakes, these days I see them as a wonderful opportunity to impress my piano teaching clients. I’m not going to say that I enjoy making mistakes… but I certainly don’t dread them.
