If work is frustrating on monday, hold your peace. An associate can help you decide how to handle it in the most professional, effective way on tuesday or wednesday. Moreover, these are excellent days to take the initiative when dealing with problematic issues. Billing and accounting aren't your favorite areas, but tackle these tasks at the end of the workweek and they'll go much more quickly than you'd expect. Engage your intellect this weekend with reading, a lecture, art, or games and spark some energy that will carry over into the business world with great results.
