One of my favorite videography channels is “DSLR Guide”. He’s a young English kid who’s very thorough and makes great content. He also doesn’t have a capital P youtube personality that many seem to pull, just a passion for all things videomaking.
Another quick self test is to look deeper at your favorite content and try to emulate it for a video to see what it takes to match or come close behind the scenes. I’m a big fan of “I Like to Make Stuff”'s videos. Bob’s projects are mostly run of the mill woodworking related, but his editing is top notch (for YouTube) and I think that has played a major part in his success.
Hope this helps!
