Smoke Detectors, coffee shakes, and multiples.
9. When you find your rhythm, a smoke detector will start chirping. And you won't be able to figure out which freaking one it is.
10. Having the shakes from too much caffeine only occurs during the detail drawings.
11. Working in multiples takes the preciousness away from any one piece. So does knowing that if you keep avoiding getting back to the 'started one' that you love so much and are afraid you might mess up, it's just going to stare at you awkwardly, in that 'bore-a-hole in your soul' sort of unblinking way. At that point it's worth screwing it up, even if to just gouge it's judging eyes out.
