Learned as a writer but it applies to all art: Your skills will plateau and you will feel like you're backsliding and everything you make sucks. This usually happens shortly before your skills take a leap upward. It's your brain trying new things and figuring out how to do them.

Something I always tell my students is that when you're making fundamental changes to improve at your craft, you will always get worse before you get better. Gotta climb down from that plateau first before you can climb up to a higher peak.

I found this really cool graphic that illustrates this a while ago, and I show it to my students all the time! Your point exactly.

Weird afterthought on reading this-this happens to kids too. Like, just before each of my kids tipped over into literacy they looked like they were sliding back, avoiding reading, fighting then BAM. went from sounding out words to just being fully literate practically overnight.
