Well, it's official. I wasn't quite able to finish.
My scope was good, I just didn't follow the common wisdom to build in 20% margin for time overruns. If I could have taken a day off this week, it would have gotten done for sure.
But I'm not mad. Jams push you on every front and reveal to you where your weakness lies. You can be mad about this and scrap your efforts, or you can use it as a ladder to make the climb up to your next level of aptitude.
For all the others out there who couldn't quite make it: I see you. Don't worry--we'll get 'em next time.
