I've learned to work with chaotic schedules. It's a part of my routine. In fact, when I look at a schedule, I know that it's a schedule with potential failure. I've rarely had projects with even supremely scheduled activities NOT have one hiccup or another. You just never know. I like to think that one failure of ours is that when we plan, we forget to plan for failure. Giving yourself some margin to breath is a way to minimize stresses on you when unplanned events occur.
Thank you for sharing.
