I thought of a new word today: incrementality. It's the state of mind that I (and surely many others) get into when they do things in increments - e.g. weblogging. Since it only takes a few minutes to add a link, I don't feel like I'm wasting time completing one increment, yet I almost always end up spending an hour or two with subsequent increments. By contrast, if I have even a small project to do (1-2 hours), I'll tend to put it off.
I'm not sure if I need to incrementalize my mini-projects, or just get some motivation to sit down and do it. Weblogging definitely has incrementality going for it, though.
