Totally agree on this. The low-hanging fruit isn't squeezing in a couple more hours, its improving the quality of the hours you currently have. If you can do 8 hours every weekday of truly productive time spent focused on the right things you'll run circles around most of these 100-hour-week braggarts anyway. Of course if you are truly god's gift to white-collar workaholism then sure those additional hours can add up, but if you sacrifice sleep and thus cognitive function you're shooting yourself in the foot to get there and probably don't even realize it because of the haze you're living in.
