If you have to handle detail-oriented work on Monday, be sure to double-check it first thing Tuesday morning, when your mind's much quicker and your memory's firing on all cylinders. This excellent mental energy lasts through Wednesday, but at the same time, you're prone to possible overreactions. Rein yourself in. The end of the workweek is all about follow-through and follow-up; check back with your boss about project plans and check in with important clients. You may have ample work to do this weekend, but you should also plan to go out on the town and work out some tension.
