Record the nuances of one of your regular ol’ days.
At the end of any given day, when you’re just about to hit the point when you need to climb into bed to crash, sit down at your kitchen table with a digital recorder, push the record button, and start talking about your day. Begin with the moment you got up, and take yourself all the way to the point where you are recording yourself at the kitchen table. Mention names, places, things that you saw on the way to work, what you got done, what you didn’t get done, phone calls that you made and received, emails that you sent, overheard conversations, elevator banter, what you ate, the funny thing that happened on the way to that meeting. After you’re done talking, save the audio file (making sure to include the date as part of the file name) and archive it in a safe place.
