Why Do We Overcommit?

Why Do We Overcommit?: "If your appointment book runneth over, it could mean one of two things: Either you are enviably popular or you make the same faulty assumptions about the future as everyone else. Psychological research points to the latter explanation. Research by two business-school professors reveals that people over-commit because we expect to have more time in the future than we have in the present. Of course, when tomorrow turns into today, we discover that we are too busy to do everything we promised."
