I recently read something and cannot remember where. Not sure if it was here or facebook or another community. Maybe someone else has read it and can link me.
It starts by saying you have 86,400 dollars in your checking acct at the bank. You can use them as you wish but you cannot carry over any unused dollars to the next day. Then the story says your have 86,400 seconds in each day. You can use them as you wish but you cannot carry them over. Each day starts with another 86,400 seconds to use as you wish.
It was written so much better than what I wrote but you get the idea. Have you read this? Where?
