Half of learning is learning. The other half of learning is unlearning. Unfortunately, unlearning is twice as hard as learning. It’s like missing your exit on the freeway. You have to drive to the next exit and then double back. Every mile you go in the wrong direction is really a two-mile error. Unlearning is twice as hard, and it often takes twice as long. It is harder to get old thoughts out of your mind than it is to get new thoughts into your mind.
