If Tomorrow Never Comes?

I am acutely aware of my own mortality. I am involved in people's deaths on a very regular basis - sometimes, because it's time for them to go - other times, the reasons are harder to comprehend. Death, even in its most natural of circumstances is a hard concept for most people to comprehend. And when the unexpected is to fault for death's early appearance - people's reactions range an entire spectrum of emotions.

All I know is that I go to work for a 12+ hour shift. We generally spend every moment trying to prolong the lives of 12 random people - 12 hours at a time. Every once in a while I come home with a new awareness of how truly unknown the future is.

So while my world may seem overwhelmingly stressful: trying to figure out how to raise 3 kids - maintain my sanity, drive the right child to the right place, what to feed them, how to dress them, that homework is done and teeth brushed - instead of the headache that usually begins right around bedtime - what I should be doing is realizing that there are people all around me who don't have these moments... to use a work quote - you should live each moment as if it were your last because any one of us could go to sleep tonight and "wake up dead..." 

If today was my last day on this earth, with these people - would I regret the last thing I said to someone? Or the things I left unsaid?
