I first started teaching piano in high school. I was already busy with after school activities and honors classes, but I was looking for a simple, realistic way to earn shopping money. Bonus that I could do it out of my home! Making money from home was not necessarily important to me as a teenager so much as a convenience, but now as a mostly stay-at-home mom of three boys, it definitely is! And the best part is I can start teaching again at any time. You might be surprised at how little you actually need to get started. First things first, you obviously need to know how to play the piano. I had been taking piano lessons since I was 8 years old, so I had the experience necessary to teach.
