Tim Ferriss described very much the opposite mentality of that of the 22-hour-work-day SV startup scene in his book "The 4 Hour Work Week." A takeaway that I've always held close is you have to be aware of whether you are working effectively vs. working efficiently. While Netscape reached their deadline (I assume) and enjoyed a successful launch, I have to wonder if they could have made the same amount of progress by equalizing their hours of sleep/hours of work, which would have made their work hours more effective. Just speaking from school experience, on 2 hours of sleep personally I know if I continue to try working much I start making mistakes that cost me a lot of time, and my pace just slows in general.
