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!
Well, yeah, if you’re lucky enough to find an old magazine in the woods, but that doesn’t count, because it’s not usually free otherwise.
If you can’t find something to get off to for free you’re either incompetent or a degenerate
or, you know, isn’t a cis dude and wants some representation that isn’t disgustingly fetishized.
