Got this from online:

"Similar to the ballmer peak, being tired can make us focus better simply because when your brain is tired it has to focus! There isn’t enough left-over brainpower to afford losing concentration.


I seem to get the least work done right after drinking too much tea or having a poorly timed energy drink. Makes me hyperactive and one second I’m checking twitter, the next I’m looking at hacker news and I just seem to be buzzing all over the place..

You’d think I’d work better – so much energy, so much infinite overclocked brainpower. But instead I keep tripping over myself because I can’t focus for more than two seconds at a time.

Conversely, when I’m slightly tired, I just plomp my arse down and code. With a slightly tired brain I can code for hours and hours without even thinking about checking twitter or facebook. It’s like the internet stops existing.

I feel like this holds true for most programmers out there. We have too much brainpower for ~80% of the tasks we work on – face it, writing that one juicy algorithm, requires ten times as much code to produce an environment in which it can run. Even if you’re doing the most advanced machine learning (or something) imaginable, a lot of the work is simply cleaning up the data and presenting results in a lovely manner.

And when your brain isn’t working at full capacity it looks for something to do. Being tired makes you dumb enough that the task at hand is enough."

ya. i'm not a programmer but I guess I understand. In that being awake and alert my mind would be running away in lots of directions (like oh! there's a project i wanna do, oh! i can do this next time, oh! i need to schedule in whatever!, oh! i need to plan out when to meet my kids, oh! i should be doing this too) all at the same time. hahaa. yay. found another strength of ADD
