The Seven Axioms of Teaching

Today I'll discuss my foundational rules for teaching.
Happy practicing!
Hey! It's been a while, stranger (I realize that I'm the one that was gone, but please disregard). School is back in session and I've already had several thought-provoking conversations with some of my students. Thank you, Allen, for helping me with this list!
According to the Merriam-Webster Dictionary, an axiom is, "a statement accepted as true as the basis for argument or inference : postulate." Well, here are the axioms I use as the basis for my teaching.

1. Always be musical (play with expression).
2. Always produce your best sound.
3. Everything is an exercise in sound.
4. Practice is for problems.
5. If you can think it, you can play it.
6. Practice slow, learn fast. Practice fast, learn slow. (This one I stole shamelessly from Richard Murrow).
7. Be as efficient as possible when you practice and perform.

I'm sure I've missed a few, but I think the ones listed above are the most important.
What are your axioms?
Thank you for reading!
