That aside, article is actually not as anti-establishment as the author makes out -- unless your source of prevailing wisdom is from click-baity 4 Hour Work Weak style articles. But I doubt any serious founder puts any stock in that stuff. There's a lot of valuable info to be learned from high quality sources like Steve Blank's articles, or even a good MBA entrepreneurship class.
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 )
I lived in tropical Thailand for 2 years (wife had a job there; now we live in Korea). And let me tell you, you'll get bored out of your mind sooner rather than later, and find yourself "sitting here on HN" more often than you'd like to admit.
Creative people live for the thrill of being "in the zone", utilizing their potential to the max. Tropical surroundings or "4 hour weeks" have surprisingly little to do with that.
