Reminding ourselves each day that we will die helps us treat our time as a gift. Someone on a deadline doesn’t indulge themselves with attempts at the impossible, they don’t waste time complaining about how they’d like things to be. They don’t take people for granted, they are grateful for everything. They figure out what they need to do and do it, fitting in as much as possible before the clock expires. They figure out how, when that moment strikes, to say, Of course, I would have liked to last a little longer, but I made a lot out of what I was already given so this works, too.
