You're usually uber-focused, but at the beginning of the week, it just ain't so. Beware of getting distracted by minor matters that won't ultimately further your goals. Then on wednesday and thursday, you may have the unsettling experience of getting rather emotional at (and maybe because of) work. It's never inappropriate to step out and collect yourself (and it's much better than losing it). Then the more information you can gather the better on friday and over the weekend. Dig and you'll unearth potential problems as well as possible pay dirt.
