For most of us, though, the problem is not a lack of goals but rather too many of them. We make daily to-do lists that couldn’t be accomplished even if there were no interruptions during the day, which there always are. By the time the weekend arrives, there are more unfinished tasks than ever, but we keep deferring them and expecting to get through them with miraculous speed. That’s why, as productivity experts have found, an executive’s daily to-do list for Monday often contains more work than could be done the entire week.
