A certain South African missionary society once wrote to David Livingstone: “Have you found a good road to where you are? We want to know how to send some men to join you.” Livingstone wrote back: “If you have men who will come only if they know there is a good road, I don’t want them. I want men who will come if there is no road.”

I recently saw where George Washington said that most things attributed to him on the internet were not things he actually said. In that same spirit, I have no idea if Livingstone actually said this. But if he didn’t, he should have. It’s a thought worth considering.
