It's easy to be ambitious when making out the day's to-do list. There's so much to be done. However, don't be afraid to mark off things as low-priority when time runs tight. Then, if jobs go quickly, you might work in one of the low-priority items. If not, don't sweat it. That's why they are called low-priority, so we can bump them without regret. Try it. You'll end the day more refreshed when you do.
