Your most taken quiz doesn't have to be your favorite quiz. If your favorite quiz is everybody else's favorite quiz, what is the point of having a variety of quizzes? Everybody else's favorite quiz would be one topic, and how is that fun? Don't complain about your favorite quizzes not being your best, just make quizzes that make you feel happy. The goal in this world isn't supposed to be easy, and it is also not to be the absolute best.
