* Get less scared about applying to do stuff! I'm leaving my longtime job---I've taught advanced math to super-smart high schoolers; I'm quitting to be a visiting professor at Deep Springs College for a semester and then ???---and in the past, fear of applying to things (jobs, grad schools, writing residencies) has been a major blocker.
* Learn complex analysis!
* Get a better workflow for writing my notes to myself (e.g., Obsidian) and for publishing my blog/website (have a marginally-functional Hugo instance right now). Small thing, but the kind of important-but-not-urgent thing that it's easy to put off!
Out of curiosity, why are you quitting teaching? If you’re a high school teacher, I have to assume that it’s not the money.
