pfft... All I see in the article are 8 unproductive hours every day. Research has shown that humans really don't need 8hrs sleep to work at their optimal best and 4-5 hrs of sleep should be more than enough. He could use those extra 4 hrs every to further develop the companies or even better try launch another startup on the side. Also walking 2 blocks every day between the two companies? That seems a waste of time which should be spent working, I know it doesn't sound much but walking two block every day adds up as a ton of wasted time. He should iron that inefficiency out of his schedule by having a common office for both jobs and using skype if he really needs to talk to someone. Also taking weekends off? Don't even get me started on that.
