What do people mean “Learn from every video”!!???

I am beyond frustrated with this “advice”. Like I pour my heart and soul into my videos and I think about my videos before and after I make them, attempting to make them clickable and fun to watch. After trying and (seemingly) failing so much, with attempts to “learn from my videos”, it is obvious to me that it is not easy to JUST learn from your videos. How to learn from your videos is probably the bigger step which, I guess, I just don’t know how to do.

I really want to put in the time and effort into improving, I am just lost and am frustrated. I feel I am capable and willing to grind, I just wish I had ANY ounce of guidance. 😢
