He wrote code for a living. Mornings were good, but after lunch he was... foggy. Couldn't think his way out of a wet paper javascript, and would find the phrase "wet paper javascript" hilarious.
On them, he'd write notes to himself about the code which needed to be written.
By lunchtime his monitor was like a boxy, computer-faced lion, with a pixelated mane of Post-It all the way 'round.
He'd stare at that halo of notes, that corona of Post-Its, and wonder (and I'm not making this up, these are Dave's words) who had been sitting at his desk all morning.
And then he'd think that MAYBE he could follow the instructions on the note.
The thinking had been done. Now? Chop wood, carry water.
1) Figure out which parts of your job are thinky.
2) Figure out which parts of your job could be done by a monkey who has stolen your clothing.
3) Leave notes for the monkey.
