I break the problem into tiny, testable parts, then run a loop until the output is deterministic. If my head starts to wander, I step away for a quick scan of the logs—just enough to reset my context. And if the pressure spikes, I lean on a strict routine: zero tolerance for distractions, constant code reviews, and a coffee that tastes like it was brewed in a server room. That keeps the mind locked in the same place where the code is.
