You might want to put your ideas in writing. A thoughtful email, creatively worded, is a swell idea on monday. Email is, in particular, a great way to let someone know you think they've done a great job on something. The compliment will seem bigger and more official. You could use a complimentary email on tuesday or wednesday this week, something to offset your anxiety about current responsibilities, but don't count on it. Anyway, by thursday, you'll feel a lot more at ease about everything. You do a lot and you demand a lot from yourself. Take the weekend off.
