My company is also at a point where my business partner and I could reasonably step away and spend 4 hours a week literally running the business but of course, that's not what business is about, it's about helping our customers and we work hard every day to do that.
Think my "issue" here is I was one of the people who only had that source of prevailing wisdom for a long time and while I can't say it helped me create the business, it did create the dream that led to me starting, and powering through, what I currently do.
(also, while my partner and I both work hard on the project we both happen to be on a tropical island in Thailand at the moment ... but it's 8 am and beautiful and I'm sitting here on HN :-D )
