“Ever since early man first scratched his desire to “Make fire, find food” and “Don’t get eaten” on a cave wall, goal-oriented people have been approaching each new day in a similar fashion, jotting down in one form or another the upcoming tasks that require their attention.

The “To Do List” hasn’t much evolved since those dark perilous days in terms of its primary purpose: the need to plan our day and manage time effectively, but there has been a progression in terms of its complexity.”
