It has been a long time since I have read this book but I would say the moral of the Mirror of Erised is to not dwell on the past. To not focus on what you do not have and instead to focus on what you do have and make the most of it. Harry was so intrigued by seeing his family in the mirror that he no longer accepted that he was an orphan and Dum bledore had to put an end to it. Instead of dwelling on desires, make the most of what you already have.
Hope this helps! If you need any more help or further explanation just let me know! :)
Reading ready player one was ok. And I say this because the plots in the story weren’t as exciting as any other story I would read but, the thought that went into the story was good. Like how the author of the book thought of which events should come first, and what should go one throughout the story. Another thing that I liked were the descriptive words the author used to help the reader visualize what is going on in the story. The author also did well on choosing the characters personality, and how it would help in certain events of the story. And this is why I think reading ready player one was not the best, or the worst book to read in my own opinion. :)
