One of my favorite posts is Merlin Mann’s Mud Rooms, Red Letters, and Real Priorities. His main point is that adding an assortment of labels, tags, and priorities to your email inbox only serves to give you the illusion of getting work done. Either something is important, or it isn’t. You don’t need five levels of priorities to decide that, and spending time categorizing isn’t real work.

The same is true in any product. We need to get out of this idea that the act of spending time on a project means that you spent your time wisely. Sometimes you’re just wasting your time.
