Some days you have a hundred things to do and you fly through them with success and tenacity. Some days you have only a couple things to do but you want to do more. Some days there's nothing you can do even though there's still a lot to get done.
And those days might be the most stressful because you realize just how little control you have over many of the elements that go into the day that will ultimately have your name on it. You look for some meaningful lesson in all the frustration but it's late and there's no real resolution so you hop into a comfortable bed with your fiance and think "well... life could be worse."
