Also @Glisten, I'm concentrating my music teaching on teaching adults and children who are moderately to severely disabled, physically, intellectually and psychiatrically for 2 reasons, one is that learning as in studying something is a vital coping mechanism for human beings, and we always underestimate that ability in disabled people, the other is that music study rewards one with passion and is excellent for brain development.

Teaching people with disabilities teaches you a lot about pedagogy, and the need to be flexible while also setting realistic boundaries. 

I just had a student ring and say she's feeling very depressed to which I replied "Do what you can of the revision, it doesn't matter if you don't get it all done.  When we have the lesson on Wednesday whatever you haven't done I'll set week and the week after...and we can use the rest of the lesson to tidy up the bits you're not yet understanding.

I'm very impressed because this woman has ADHD as well as schizophrenia and anxiety disorder, and together we've been able build her a neural pathway for studying, it took a long time and patience on both our parts, but she now gets into her study and practice doing a bit in morning and a bit in the afternoon, then some in the evening is what works for her...and she's doing well.  Even if she doesn't get to do a full hour, she's done at least half an hour or 40 minutes through the day.
