“Childhood memories are sometimes covered and obscured beneath the things that come later, like childhood toys forgotten at the bottom of a crammed adult closet, but they are never lost for good.”
— Neil Gaiman

Begin with the well-known, but not-so-well-sourced quote that goes something like this: “All children are artists, but…” then goes on to claim that when maturity happens, love and work with it, you, the former child, are told to stop creating for yourself and begin to trade what you have acquired for what you have not.

Then suddenly—or gradually—the others you loved or worked for are no longer interested in what you can do. You are no longer valuable to them, be they a corporation or a cohabitor. Society has moved on without you. But the old toys remain where you left them. Pick them up and begin again where you left off.

It [art] has no survival value; rather it is one of those things which give value to survival.
— C. S. Lewis
