 But when I read your book, there's two things that stand out. One is know your numbers, meaning you got to have technical skill. You have to pay attention to the business. What percentage of business owners know their number? None, I'm trying to tell you really, all your successful ones and the unsuccessful ones don't know their numbers. And I don't care how good your product is, if you don't know your numbers and I can talk to somebody for a minute and a half and start quizzing you about your business and I can know real quick, you know, how much is your receivables? What's your payables? What is your cost to sales? What is your labor costs? And if they don't know those numbers, they're going to go out of business unless they just happen to have a product that is just flying off the shelf everywhere because you have to know your numbers to be successful.
