What would you do if someone gave you $86,400 every day? The only catch is that you must spend it all. Any money left over was lost, but then the next day you would receive another $86,400.
I doubt if anyone is going to give you $86,400 every day, but each day you do get 86,400 seconds, you must spend them all as you cannot carry them over to the next day.
Do you spend them all, or do you waste many of those precious seconds.
