I learned how to think. I learned how to problem-solve. I learned how to bust things up and develop a logic tree. Classic example was, someone asked me, “How many barbers are there in the United States?” Now, how would you dissect that question? You can calculate it, if you just run a number. You take the population of the United States, 250 million, you cut it in half, because half are women. Then you say, how many of those would have a haircut? Well, one year-olds don’t. How many haircuts do you have in a year? How many haircuts can a barber give in a day? Before you know it, the number spits out: the right answer, or doggone close. So, I learned how to order my thoughts, and most important, learned how to develop a plan. I discovered the power of a plan. If you can plan it out, and it seems logical to you, you can do it. And that was the secret to success.
