Yesterday was a tough day.

Black swan events emerged - things that I didn't anticipate came and kicked my butt first thing in the morning. I spent the first half of my day fire-fighting, focusing on the most important things I needed to do, and disregarding the things I couldn't focus on. A friendly smile and conversation over dinner last night helped to get things off my mind.

This morning when I went into the office I felt this sigh of relief after yesterday's kerfuffle. And I remembered the serenity prayer that perfectly encapsulated how I dealt with yesterday:

O God, give us the serenity to accept what cannot be changed, the courage to change what can be changed, and the wisdom to know the one from the other

I'm not religious at all, but this quote summarizes my feelings exactly.
