"When I first started working for my current company, I called an important client right in the middle of earnings season. I wasn't calling to provide any investment information that might have helped him; I was just touching base. The client wasn't happy that I wasted her time, especially during this extremely hectic period. I apologized and wrapped up the call so she could go on with her day. I never forgot the lesson I learned from that experience. Now I only make contact with clients when I have an express purpose or information of value to provide, and I always pay attention to the timing of the phone call."
