It can be a frustrating waste of time, believe me. I find evening calls most productive, and you do not necessarily have to give up your leisure time or time with your family. Keep a list of home phone numbers by your phone and make one call per television commercial. In regard to marking, pick the time of day that suits your energy level. If you feel most energetic during the day, and tire easily in the evening, you must work diligently during your preparation period as well as your noon hours.
