Don’t lose more than the face value

This Monday due to my hectic schedule and a small element of absent-mindedness, ICryOverSpiltMilk double- booked myself.  I ended up forfeiting a ticket to a play(theatre) for 17 pounds (non-refundable and I did not have time to pass it onto someone else).  It was not a huge sum but I was not happy about it and kept thinking about it. 

It suddenly dawned on me that if I dwelt on it, I will lose MORE than the face value of the ticket of 17 pounds as time is money.  I finally managed to convince myself to “bite the bullet” and move on.  “Don’t cry over split milk” has some truth in it.
