To be completely honest, the only reasons why Riddle is so talented and intelligent both magic and academics is because the strict rules and principles that his mother posed on him. According to Idia, he wasn't a prodigy or was he born with natural talent (He earned it through hard work). His entire life, he was already decided on what he was supposed to do. Even his parents going through the lengths of making him practice/study magic at the age of 3, reading medical documents when he was around ortho's age, and being chronically offline or outdated when it comes to social media or trends. But with the price of restricting his own happiness and freedom, he was able to strive and be capable BECAUSE of his mother's rules. That's what he believed growing up, if he was able to turn out magically and academically talented because of rules, then it must be the right way to live. He believed the true essence for success was RULES, because if it worked out for him, then it must work on other people. As someone who grew up around parents that valued my freedom and never posed strict rules on me, it hindered my talent and strive to be better. It may come across as insensitive, but I would love to have Riddle's life where rules are placed on to me for the sake of development. I don't care if I'm unhappy, as long as I'm intelligent and talented, I would love to have rules.
