The other day my self discipline failed, and after weeks of craving I bought a video game. Addictions are never broken; they are only tamed. Eventually they will escape the leash and savage a passing pedestrian. For weeks I’ve been browsing the game shops, debating the for and against of giving in to temptation. This time the for side won, but for a very simple reason: giving in to the addiction was also the best way of kicking it.
