The only teaching I did was helping some teenagers with their homework, haha! Not that impressive. But... it was the start of my stay on El Hierro and made me find another place to stay. It was totally worth it!
I even started a big movie project there which, unfortunately, has just been cancelled (after 9 months). It was the best decision though.
Yeah, in teaching it's all about focus and progress/ the process and for me also about energy/ effectiveness. It's very hard to reach them all and help everyone out.
I understand your reasons for feeling better in a different place. Although I think people can probably feel the same in many different places. Anyhow, if it feels good, definitely follow through on it! ;)
