I have never seen a one-sided coin. But all too often we forget that fact. We often think the side we are on is the only side or the right side. When we do that, we may be smart, we may know our facts, but we also may be limiting our intelligence. God did not give us a right foot and a wrong foot.
Humans make progress by first making a mistake to the right and then making a mistake to the left.
People who think they must always be right are like people with only a right foot. They think they are making progress, but they usually wind up going in circles. I think as a society we need to be more intelligent with our strengths and our weaknesses. We need to learn to operate more intelligently from our feminine side as well as our masculine side. I remember when I was angry with another guy at school back in the 1960s, we would occasionally go behind the gym and fight with our fists.
