A room where you fail politely, over and over, until you don't.

means A dedicated space for practicing a martial art or discipline, typically under formal instruction and etiquette.

from From Japanese 道場 (dōjō), literally 'place of the way' — combining 道 (dō, 'way' or 'path,' the same character in judo and karate-do) with 場 (jō, 'place'). The term originally named the spot where a Buddhist sought enlightenment, often a hall attached to a temple, before martial artists borrowed it for the halls where they pursued their own kind of discipline and mastery.
