Every interaction with someone is an opportunity. The thing is, you never know exactly who you're going to meet, and you never know exactly what that person will be interested in. That's why it's so important to keep up with what's happening in the world at large, in areas outside of sales and outside of the markets to which you sell. What great books have been published recently? What are the most popular articles online right now? What are the headlines for countries around the world today? Be on the lookout for ways to constantly draw new information into your daily routine. This constant stream of information will help keep you agile and prepared for interactions with anyone you might meet.
