Everything you make is limited edition.
The crummy poem you shudder to look at. The little stick figures all over your math. The magic-marker doodles on your favorite shirt. That weird breakdance move that keeps straining your ankle.
You are the only person on earth who can create something created by you.
Others can imitate what you create, or you may imitate others, but what you do is special simply because nobody else can ever create it just like you do.
And once you're gone...
Nothing can ever be created by you again.
