A commander in chief ought to say to himself several times a day: If the enemy should appear on my front, on my right, on my left, what would I do? And if the question finds him uncertain, he is not well placed, he is not as he should be, and he should remedy it.
When we treat people merely as they are, they will remain as they are. When we treat them as if they were what they should be, they will become what they should be.
