I feel like I have heard this quote somewhere, but can't remember where or by whom. I saw somewhere on this site something along the lines of "a good definition is worth a thousand proofs", but that doesn't sound quite right and was unattributed. Anyone know what I'm talking about?

Maybe you were thinking In mathematics: One good definition is worth a thousand calculations. – Amzoti Feb 19 '13 at 21:05
@Amzoti maybe. I had thought there might be a particular person associated with such a quote, but it might just be a common saying instead? – usul Feb 19 '13 at 21:24
I have tried looking and no luck either! Regards – Amzoti Feb 19 '13 at 21:29

You know what, it was probably this:

A good lemma is worth a thousand theorems.
