You'd be wise to concentrate on work on Monday; save the sweet little IMs and online flirtation 'til after-hours. Let a trusted, emotionally intelligent friend in on a certain hope around Tuesday and Wednesday, and listen to their opinion on it (even -- or especially -- if it's hard to hear). Then show a certain someone that you're capable of zeroing in on them at the end of the workweek; they'll feel very special getting more than your usual short attention span. And this weekend? Wow -- you're hot stuff, and everybody knows it.
