2 reasons even after 10+ years of doing Blender I still watch “beginner” tutorials occasionally. 1) To become a master, you must master the basics 😀 (a concept I heard about in relation to martial arts, but really applies to just about everything.) and 2.) You never know when you might learn something you didn’t know or hear something explained in a different way than you have before that makes something make more sense. Even if it’s from someone you’ve watched beginner tutorials from before, they’ve learned more on their journey and may pass on insights they’ve learned. Not to mention different people do things in different ways so you might learn a new trick, a new tool, a different way of doing things that you’ve never thought of before.
Another thing I learned a long time ago is to treat what I’m learning like canned spinach… If you like canned spinach, then by all means you grab some, but if you don’t like canned spinach, you don’t have to take it off the shelf. But just because someplace sells canned spinach doesn’t mean that there aren’t other things in the store that I want. So if I’m watching a new tutorial and I don’t agree with something, I look for what I can learn or what resonates with me and leave the things I don’t want “on the shelf” so to speak 😀
Also, lots of great intermediate tutorials on here, depending on what your long term goals are. Kent’s tutorials are usually great, especially the SESSIONS ones and HUMAN.
