It’s okay to make a big purchase at the beginning of the week if the investment is going to pay off in a big way; it’s okay to be flashy if you’re doing it for the cause of something meaningful. Of course, a value discussion with your colleagues may be in order. A couple of days into the week, a disagreement with said colleagues could really throw a wrench into things, but steel yourself and remember to listen with an open mind. As much as you may want to rush ahead on Thursday and Friday, it isn’t necessary. Things take as long as they take. Go with the flow this weekend.
