I never had burnout from writing code; I had burnout from PM changing priorities every day or from tickets being half-baked. Also been burned out from being awakened that switch in somewhere in the Middle East had high CPU usage, which I was on call for for some reason (I wasn't on the network team, but that team didn't have bandwidth to be on call)

Writing code is easy; that's why I do it as a hobby on weekends as well. I don't have to sit through five arch review meetings that talk about how we are going to name the class rather than what the API contract is supposed to be.

Sure, writing good C is hard, and writing PHP (used to be) hard because language design is full of inconsistencies. There is so little "hard" code that I wrote for money. Plenty of somewhat harder things that I wrote for myself because it's entertaining. There was a time when I had to spend more time getting a pull request ready than actually writing code in that PR.
