As a well-spent day brings happy sleep, so a life well spent brings happy death.

Rest at the end of anything depends on how the hours before it were filled. A day spent on what mattered to you settles easily, while a day spent avoiding it keeps you awake with a vague unfinished feeling. Something like that quiet accounting seems to run over a longer span too. It is not a ledger of good deeds, and it is not a warning. Peace tends to follow from having spent yourself on what you actually cared about.

Take one evening this week and ask what made the day feel finished or unfinished. Then put a little more of tomorrow toward whatever answered that.
