I don't have a question, I just wanted to say this intro is beautifully done and a great commercial for Blender!
The advice at 6:30 is excellent: watch a course, then watch and work through it, then try it with no guidance. Sometimes the excitement of a new course makes it hard to resist jumping right in but sometimes it is nice to have primed your brain by just watching (especially if it is a new topic for you).
Absolutely! LTS versions are generally the best to go with if you want to take your time learning, as they provide support (bug fixes, mostly) beyond the next releases. This is important in a production setting where there is a "version lock" when a project begins, so that everyone is on the same software. New features are tested in the intervening versions, but it usually isn't until an LTS release that they are well-documented enough and have good support.
