I was thinking about One Hit Wonders.
We're very hard on them, don't you think?
Is one only truly legit if one's successes are plenty?
I hope not, I mean, imagine a world without the Macarena or Ice Ice Baby - the thought alone is a sadness.
Honestly though, there have been a few times after I've finished a book or a sandwich and I've thought, "If you were put on this earth just so I could read this book or eat this sandwich, it makes perfect sense."
Fun fact: Black Beauty, Gone with the Wind, Memoirs of Geisha, To Kill a Mockingbird - apparently, these lovely books are the only ones each of the authors has ever published.
