What's yours is yours, and especially so for the first couple of days of the week. Hang on to materials and territory fiercely, even if it causes friction with your teammates or colleagues. By midweek your sweet nature will be back in force and you'll be able to patch up any problems that linger. You'll also come to a vital realization that you need more information on some arcane topic. The weekend will be a good time for chilling out and taking stock of your current situation and strategic options.
