Set up a calendar invite for yourself to go back and review calls at least once a week.
- In the calendar invite, note prospects that you had particularly good/difficult conversations with so you know which calls to come back to
Set weekly review for a 'down' part of the day (after lunch is usually a great time)
Create a library of your best calls
- Listen to one at the start of each day to kick off the morning
Please see Creating Library - User Experience on how to create a personal library folder.
