It's very great post, @fun2learn, as always! in relation to find our interest in teaching, I love singing very much. so I'll try to connect this passion to the way I teach my pupils in English class. Every teaching materials must have a connected song. So, before teaching-learning process, we usually sing the song. And the students look enthusiastic in learning then.
That is a great way to teach using your love for singing! Good job and continue to engage your students with your interest!
