Have there been times where I was stressed and working long hours to get everything done? Sure. Has it ever been anything near 80 hours in a single week? No way. I can feel my mental sharpness decline in the late afternoon, and the best way for me to push past eight or nine hours of work in a single day is if it’s on a completely different project, like, say, a board meeting or an article for an outside publication. Long hours should be rare, because productivity always takes a hit afterward.
At the end of my days I often read a few things and link to them…like right now. It’s good to sort through the article collection from the day and it doesn’t take the same mental power of deep development or writing.
Then on the relation to a sports team and working long hours:
Training 70 hours a week would be a nonstarter. Even if NCAA didn’t regulate training hours, it would be such an obviously bad idea that any coach proposing such a schedule would be fired immediately. Great performance in athletics requires short bursts of concentrated, intense effort, followed by rest and recovery. That’s why using elite athletics to justify long hours is so foolish.
