Unfortunately, many of us have a measure of our success or failure by what we accomplish each day. We have lists of things to do. If we hit 5 out of 8 tasks, we might see it as a good day because we did the majority of what we set out to do. Others look at what wasn't done; what was the proportion less than 100%.
I think that it is better to hit 5 out of 8 than to do a list of 48 and hit only 12. Keep the lists reasonable. Don't be ashamed of "loafing" once in a while. Maybe because I'm getting older and closer to retirement age, I'm accepting the need to take a nap each afternoon (because I CAN), and to have a Sunday once in a while where I just read, watch a game on tv and vegatate.
Unless procrastination leads to financial or personal problems, give yourself a break once in a while. That's becoming my motto.
