One of my favorites from Mark Twain,

Mark Twain's answer to a would-be writer:
"Young Author"--Yes, Agassiz does recommend authors to eat fish, because the phosphorus in it makes brain. So far you are correct. But I cannot help you to a decision about the amount you need to eat--at least not with certainty. If the specimen composition you sent is about your fair usual average, I suggest that perhaps a couple of whales would be all you would want for the present. Not the largest kind, but simply good middling-sized whales.



And Albert Einstein..
