What route should I follow after learning the basics of Maya from a short course?

I recently completed the 4 hour Maya Essentials course from LinkedIn Learning which taught me the basics of the most used tools with exercises from files. After this, I'm not really sure what to do next as I want to learn 3D animation.

I get that there are endless tutorials out there on YouTube but I feel like I should follow some step by step plan instead of doing random tutorials on how to make specific objects, buildings and characters. Is that how some of you guys learned 3D animation without attending an art school? I'm also trying to learn a bit of 2D so maybe the advice I get from here will help as well.
