They sit in the stands at the stadium and call out the instructions that they think are right to the people on the field, and of course none of the people on the field hear what they're saying or care. They may know themselves very well but they take no action to grow. If all we do is become more enlightened, but it doesn't spill over to affect our behavior, we end up being an armchair quarterback in a very lonely situation.

It's as if they're running on a treadmill trying to win a race that doesn't exist. They keep turning the speed up thinking that somewhere in the distance, they're going to win.

In a word, they're competing.
