My father in law (deceased) used to spend 8-10 hours a day doing woodworking art for his business, then several hours delivering things to customers each day as well. I asked him how it tool 8-10 hours to do 3-6 pieces when I had been watching and he finished each one in about 30 minutes (other than paint drying and stuff). He said that people were always talking to him, because his store and work area were basically right in the middle of town and he worked out front rather than inside because he had no workshop in the store. I hung out with him for a day and saw no less than a dozen different people stop by and have 10-15 minute conversations with him, and he couldn't do much work during that time.

That's a pretty useless story for HN, but seemed relevant to the topic at hand, and I like remembering my father in law and telling stories about him (I miss him considerably).
