If, like me, you have trouble doing things that you say you'll do (sending those thank you cards, fixing that faucet, putting together that Ikea shelf bought four months ago) and tend to put things off until an undetermined date, then you have what is called "manyana disease" -- more commonly known as the penchant to procastinate.
Indeed, it's a ruinous disease (a silent killer) that has likely afflcted all of us at one time or another (either at the workplace or at home) and yet its causes are largely misunderstood.
This is the starting point of "Later: What does procrastination tell us about ourselves," an enlightening and fascinating piece in the current issue of The New Yorker by the magazine's financial columnist, James Surowiecki, who puts to bed some of the misunderstandings of the roots of the disease, if not the disease itself.

Different factions contended, short- and long-term interests were entrenched in mutual loathing. Not only were motions tabled and opposed, certain proposals were aired in order to mask others. Sessions could be devious as well as stormy.” Similarly, Otto von Bismarck said, “Faust complained about having two souls in his breast, but I harbor a whole crowd of them and they quarrel. It is like being in a republic.” In that sense, the first step to dealing with procrastination isn’t admitting that you have a problem. It’s admitting that your “you”s have a problem ..."
