Exactly.  The essence of teaching, its central skill, is the ability to find people where they are, and empower them through their learning.

And see my earlier post from a year or two back. Again, while seeing the immense value of classical music, I could not disagree with Malone more, and think that all musicians in public forums should have a healthy respect for music of all kinds.
