If it hasn’t [already] been done, and if it’s of value, there’s really good reasons it’s not being done. And so when you’re confronted with those reasons, you’ve got two choices: You can say, “Oh, that’s a very good reason. I’m sorry for bothering you.” Or you can say, “I don’t believe that. I’m going to find out more.”
