Very good thoughts in your article, but I don’t agree with this one. The problem with this “getting ahead of the week” is that it tends to escalate — first, it’s just making a game plan. Then, clearing out a few pesky emails. Next, just a half hour put into something you didn’t wrap up on Friday. Before you know it, your Sunday afternoon has become part of the work week.
My approach is: If you absolutely have to get ahead of the week, start half an hour earlier on Monday. Maybe it’s because I tend to work better in the mornings, but a distraction-free time slot before everyone else shows up does wonders for me in terms of planning and getting a head start on the most difficult tasks.
