I call this the painting problem. Painting the walls of a room seems easy to an amateur: You just buy a few gallons at Home Depot and slap it on. But a professional knows that prep, trim, and cleanup are 80% of the job and they take skill. Anybody can slap paint onto the middle of a wall. What's difficult and time-consuming are making the edges sharp and keeping paint off the damn carpet.
