I’ll start by plugging Harvard’s free courses catalog as well as Udemy
Edit: Gonna add 2 more I remembered-
Blender - I wish I had more time to learn it, but I did start the infamous “Donut Tutorial” once!
Watch Cartoons Online - Lots of good older stuff!
I moved to a new town in 2022 and I STILL haven’t been to the local library. I need to get on that. I went to libraries so much as a child and in my teens.
