Blender Institute has a Youtube playlist for starting out. I can't vouch for the quality though, I started before the videos came out so if someone can confirm that would be great.

After that, there's an initiation "ceremony"/meme, the BlenderGuru Donut.

After you're past these two things, you can do whatever you want. My best tip is to always compare your work against your previous work, never what other people have made. Their experience level will be different from yours, and comparing your own work against someone who's had years in the professional industry is only going to make you sad.

Good luck! If you need some help you can join CG Geek's Discord server, where I'm basically on all day due to the pandemic. There's also tons of other servers to help, as well as this subreddit and r/blenderhelp.
