Benz recommends embracing knowing when to stop!
"For now, the house is complete. There is always more to do, and perfections to be made — for example, millwork and built-ins, and additional moldings — but my Parsons' education necessitates knowing when to stop, and always leaving something unfinished. For example, the stairs were untouched but completely worn and weathered from 100 years. That makes me feel great about the freshly painted black lacquer trim. Re-doing the stairs would be too much."
