I've heard Elon Musk say this a lot. It seems to work for him, at least.
Programming requires a lot of concentration that is hard to sustain for a long time (the author of the post is an iOS programmer).
(In the vid he's saying he used to sleep on a futon in the office as he couldn't afford a flat at the time)
What gets me is recovery. I would be unable to run hard for a week after that. Younger pros do like 5 or 6 really hard workouts a week. Older pros a bit less.
I totally would follow them but my body cannot recover between workouts. In my opinion what makes a world class marathoner is not his ability to work hard, it's a special gift to recover. I would work just as hard, but I physically can't as often as they do.
Saying anyone can be an elite marathoner by running like an elite marathoner? Bull. Any decent runner can do a workout or 2. Then you need a week to recover.
What does all this have to do with programming? Maybe nothing. Or maybe what makes the super productive guys so good is they mentally recovery faster? No idea on programming front, but I am confident on the running front it is all recovery.
I'm a programmer, and I don't know how it relates to what I do, but I've already set my mind on finding out.
--edit
Imho the core of this idea is that "recovery" applies to many things: how early can you get another 4-hour coding session? How much did the first one tire you out?
How well do you recover after a failure? Bug in my code? I jump on that immediately and don't think twice about it; an argument with my girlfriend / co-worker / boss / parents? Not so much.
I believe you can train both your body and mind to get better at this; get better sleep, see a therapist.
Even more, you can tweak life's settings to work in your favor: a stable relationship, better/quieter housing (or job), savings etc.
You can quit a job, but you can't quit a calling!
I would imagine we've all been on death marches at some point in our careers. And yes it can work to meet a deadline but the long term result is usually burnout and piles of technical debt which is always less fun to work on even if you're motivated.
+1, many times over.
Taking breaks and having fun are very important to maintaining high productivity and creativity when I am working. Unfortunately it's in stark contrast to the mantras I often hear suggesting "there's someone out there who is working harder than you on the same thing and they're going to win if you let up." That mentality is unhealthy and leads to depression/exhaustion.
