After reading that article a while back, I started making longer to-do lists. I found that it's hard for me to do a task on a three item to-do list. But if my list has 20 items, it's somehow easier to pick an item from the middle of the list and bang it out.
Amazing that after a distinguished career as a respected philosopy professor at Stanford, Perry's greatest contribution to humanity may be that humorous article on procrastiantion.
