Monday or Tuesday is a good day to review a budget and figure out new ways to trim expenses. You’re feeling unusually thrifty, and your eagle eyes can zero in on wasteful spending. Wednesday, you could have a chance to strengthen your rapport with a co-worker. Don’t worry if idle chat has a tinge of gossip. If your schedule permits, an informal meeting after work might not be a bad idea. Friday, you should take the time to reevaluate your approach to a particularly challenging task.
