"Either you've lost it, or you never had it to begin with. It's not just imagination.
Were you worried about bills, a mortgage, utilities, and your career as a child? No. You thought that grown-ups worked for money, money paid the bills. If you grew up poor, you might have had a small window into reality, maybe you heard you parent(s) talking about a late bill or were told there wasn't money for extras like ice cream and toys, but you didn't fully understand it.
Children just see the world differently. As a kid, you may realize that your friend is the smelly weird kid in class, but you don't care. He likes Power Rangers, you like Power Rangers, done deal, he's your friend. An an adult, you may avoid the smelly weird guy at the office because he has poor hygiene and a mental disorder.
By the time you're an adult, you've seen some shit. You have life experiences that form the way you view the world. Children are a clean slate. Ever notice you can lie to a child and they totally believe you? They have no reason not to. Mistrust and deductive reasoning don't get in the way. The world to them is simple, yet full of magic that they hope to learn someday.
That's the problem though. We grow up and a great many of us forget that there was ever magic. We become jaded and beaten down by adult responsibilities. I never forgot. Jim Henson never forgot. Fred Rogers never forgot. Bill Watterson never forgot." - FlibbertyGiblet
