My Dad (a wonderful man and very smart investor) always would say when growing up:
"Son, there are two types of people in this world.....One type you can sit-down and reason with, and the other you will need to smack in the head with a 2x4".
He wasn't inciting violence, and back when I was 10 years old I really didn't know what he meant. After 43 years of life experiences I finally get it.
