There's no mission without margin

A great quote from the newly nominated Secretary of the Interior, Sally Jewell, via NPR.

You know, there's no mission without margin. If you can't run a healthy business, you're not sustainable. If you can't do the things that, you know, we aspire to do in a profitable way, you will be out of business

I like this linking of sustainability with margin. I like it because I think in most instances it is true but overlooked or ignored.
