Exercise: Tweet from your phone all the conversations you hear from the backseat of your car. (Thank you for this tip, Sara Donovan-Boster.) You can even record conversations at the dinner table, while watching TV, or while watching the stars with friends or family. Record the conversations on your phone, on paper, on a tape recorder, etc.
Goal: When you record the conversations while they are taking place, you are already providing the perfect content for a great story. Put these recorded conversations or even just excerpts in a family yearbook, on a poster, or in a card.
