If you knew you had only six months left to live you would become super focused. You’d quickly realize what’s most important to you. And things that used to bother you wouldn’t bother you as much.
Imagine if you knew you had only 24-hours left to live. You wouldn’t even have time to be angry or negative. You’d likely become more prayerful, and more focused on positives.
Since we don’t know when we’ll die we act as though we’re going to live forever. We waste time, as though it’s not our most precious resource. And a lot of that waste involves making ourselves unhappy.
