Let me tell you a secret

You will never be perfect. You will never be the most successful, the most beautiful, and certainly you will never be the youngest. You will never make all the money in the world, you will never be the "best version of yourself," at least not in terms of eternity. You can pursue the endless chase of self-improvement. But if the goal of these efforts is to have a dumb audience give you grades, then, alas, those grades have long been embedded in your brain, so other people's opinions don't matter at all.
