An African proverb that I think of often says, “If you want to go quickly, go alone. If you want to go far, go together.” I used to think it was an indictment of the solitary runner who wanted to go quickly until I realized that speed and distance are morally neutral objectives. There are times when we need to go fast and there are times when we need to go far. Some people need to do each more often than the other.
