[PaperclipTaken]

Anecdotal evidence is not scientific, but this makes a lot of sense in the context of my life. At work, when I hit a tough problem, I'm much more likely to tab over to HN or reddit, yet I've found that somehow I manage to hit the deadlines at the same pace regardless of how much I force myself to focus.

I do think though while you might be drawing from one 'pool', it's a pool that you can work to expand. To me this seems to be the same vein of psychology that makes ADHD medicine ineffective for kids on the long term. There's one pool of resources you are drawing from but like muscular strength you aren't doomed to your current limits.

Yes! My pool was quite drained 1 or 2 years ago, but I managed to enlarge it by taking longer breaks, shutting down completely on weekends, eliminating foods I'm intolerant to (gluten & lactose inflame my gut pretty quickly), introducing intermittent fasting (no food until noon), adding fish oil and vit D, switching from cardio to HIIT workouts, and keeping caffeine intake constant. I can now be highly productive for at least 7-8h per day, and then still focus on my family (vs turning into a couch zombie). Lack of sleep (< 6h; optimum is 8h) still kills me though.

I think intermittent fasting and fish oil did the most for me in this regard. Since quality of sleep is really important to my focus, it might be worth mentioning that zinc supplements do a lot for me here (but at least this remedy is purely anecdotal).
