At one point in the article he says, "When I was a carpenter, I once worked with this Russian lady architect. I would tell her, 'Look, I'm terribly sorry, but I want to change that a half-inch,' and she would say, 'No limit for better.' I think that is a worthy credo. You keep on going until you get it as close to being right as the time and patience of others will allow."
No limit for better. Now that's good advice for a Monday.
