GW used to tell me, “Wear a hat, or your brains will cook.” To protect the head, but I cannot say if the brain cooks. And my little passive-aggressive attitude caused me not to wear a hat.
GW was an intelligent man. Probably he knew the brain would not cook. So what was the reason for this frequent statement? Maybe a mild disciplinary push with the passive-aggressive Doc.
More likely, GW was suggesting that one must protect one’s innermost thoughts, ideas, and plans. Keep them covered until time to reveal and put them into the pressure cooker for public consumption. Surprise increases the possibility of success.
