There was a great book written by Oliver Burkeman, 4,000 Weeks, which looks at the timeless tension between living in a world that tells you you can be or do anything you’d like and your own mortality.
There’s another way to look at it too.
David Goggins looks at his days as trying to win 86,400 micro battles for every second of the day. Think about it - it only takes one second of anger to ruin an evening with your family, one second of lax effort to decide the fate of a 60 minute football game, or one second of distraction peaking at your phone to get you in a car accident.
When I boil it down, there are probably four or five “seconds” a day that my reaction to will decide how the other 86,395 seconds will go. A driver cuts me off, do I flip out with my kids in the backseat? My son chucks hit toy at his baby sister, do I overreact? A piece of cake in the fridge late at night beckons, do I wolf it down?
Big doors do indeed, swing on small hinges.
