By the I knew Arrington (mentioned in the article) prior to Tech Crunch. He worked very hard to try and convince me to join Pool.com writing multiple times and not taking no for an answer. Back and forth, negotiating all of that. And I'm glad he did because after agreeing to get involved we made a ton of money from that service for years. I owe that all to the effort that Mike put in and was able to do so because of the hours that he worked (as well as the hours that I worked which was "all the time".)
[1] The problem is people don't realize that some people can work all the time, actually enjoy it and not be stressed. Just like some people can exercise or can climb mountains or swim fast or practice piano or anything else. Just because it burns one person out to work 7 days don't assume that it burns everyone else out to do the same. If you are exceeding your limitations and can't take it don't assume that everyone feels the same way (although they might..)
