““Nothing was more valuable than “windshield time” with my manager riding shotgun in my car. He would alternate between preaching sales theory to quizzing me about product knowledge or what was happening at each of my key customers. When we would pull up to an account, he always insisted I drive around the building. He would say, “You can learn a lot more about a business by watching what’s going in and out of the back door than the front door.” So, of course, twenty-two years later, I’m still sneaking around the back before sales calls and mentoring salespeople to do the same.””
