What about incentives?
I don't see why we as teachers should plead with the student to "become motivated".
Besides, you mentioned not too long ago that you don’t take children as students because you don’t know what to do with their lack of motivation . . . so, you don't need to worry about it! https://www.pianostreet.com/smf/index.php?topic=49251.msg536424#msg536424
When I was a child first learning piano, an incentive for me was to be able to learn something I really wanted to learn along with the pieces I "had" to learn.For me, it was boogie-woogie! lol
