No one has all the answers, although a wise colleague or manager can certainly act as a guide on monday or tuesday. Even if their opinion sounds like bunk, rein in your tongue. It could be you're not quite ready to see the wisdom in their words just yet. Beware of overworking on thursday or friday. Taking one for the team doesn't really help if it permanently burns you out. Try to keep work socializing out of your life over the weekend. If you can, opt out of a coworker's get-together and spend time on a long-neglected personal project so you can refresh your spirits for the workweek to come.
