If I have a dollar and you have a dollar, and we each give each our dollar, we still each have a dollar. If I have an idea and you have an idea, and we share our ideas, then we each have two ideas. These ideas we have in our heads will influence what we do. So, we must be careful who we listen to and we should challenge these ideas in our own minds.
We have all been at an auction and we see someone buy some cattle and our first thought is, “good luck with that” or “that will never work.” When a commodity is sold an idea was sold.
