The ultimate programmer betrayal—your brain waits until you're horizontal to unleash its genius. Eight hours of staring at the screen? Nothing. The second your head hits the pillow? BAM! Your subconscious pulls the solution from some neural filing cabinet it's been hiding all day.
That smug little brain even has the audacity to mock you for not seeing the obvious fix sooner. Meanwhile you're lying there at 3 AM contemplating whether to get up and code or pray you'll remember it tomorrow.
Ten years in the industry and I'm still having midnight standups with my cerebrum. The real sprint planning happens between REM cycles.
