A wise business practice is to become a prolific note-taker if you aren't already. When you've had a great conversation or interaction with someone--whether it is on a conference call, Skype, in a meeting, or even in passing--jot down a note or two about your time together. Then you can reference it the next time you see each other or speak again. Since most of us don't have as extraordinary a memory as my friend Teresa Palm, taking notes is a smart and easy way to show that you are interested and care.
