I usually average 40-60 meetings with prospects or clients every week.
I find half of the planning I do on Friday and the 2nd half of the planning during the weekend.
What about you?
I think it also depends on what one has to plan for! If I have to plan development and marketing activities, I prefer to do it on Monday morning with a fresh mind!
Sunday is usually the day. After an all-day rest, my mind is now clear, and I can see what has to be done in the next week, as well as make the proper plan to start fresh and focused :D
During the weekend. Without the timelines of an office, I sometimes find myself being super productive on weekend afternoons If I am at home. This translates into some planning that goes into the next week.
