How often have you been sitting in the car after a sales call, and you thought of something you should have done that would have been more appropriate than what you just did?
"I shoulda said...," "I shoulda asked...," "I shoulda...," "I shoulda...," "I shoulda..."
You make a mental note of the shouldas...and then what?
Nothing!
With everything else that goes on during the day, your shouldas become a distant memory—lessons that could have been learned, but were lost instead.
