What have you learned?

This post by Clarissa has been very inspiring to me. I have been obsessing all of 2018 about not being a musicologist and thus being dubiously qualified to write this book I want to write on music.  Clarissa writes:

 I wanted to write an article about film but I was completely ignorant about film theory. So I took a couple of weeks and taught myself film theory.

The article was accepted for publication with cosmetic changes 15 minutes ago. Both reviewers praised my deep knowledge of film theory.

I don't doubt this at all. Intellectual humility is all well and good, but it is possible to learn some basic things to a level of competence and participate in intellectual discourse at a high level after a short time. Thanks to this post I have stopped worrying about my lack of musicological chops.
