Some old guy once said "Youth is wasted on the young." This is supposed to imply that it's impossible to truly appreciate youth until you no longer have it. I would challenge this assumption, and even argue that the opposite is true: no one is better-suited for youth than the young.
As evidence, I would cite observational data: Have you ever seen a young person? They're running all over the place, trying to experience as many fun things as possible in the short amount of time they have. Children know instinctively they won't be young forever. That's why whenever you see a child at church, or in school, or some other place they don't want to be, they can't sit still. They have no patience. Every precious minute they're not playing and enjoying their childhood to the fullest is like torture to them.
"Towelie" is a season 5 episode of South Park that features a pot-smoking anthropomorphic towel. One of the running gags in the episode is the four kids calculating the number of consecutive hours they can continue playing video games before they have to go to school, or do any other activity that doesn't involve video games.
This desire to whittle one's life down to only the activities one enjoys most is emblematic of childhood. Only someone who has experienced so little time as a child can see the flawed logic in this approach to time management. For an adult, instant gratification all the time only brings eventual disappointment. Only children know how to appreciate that, because they intuitively understand another epigram that needs a few words cut out of it: Time flies.
