The Stoic technique of negative visualisation is, precisely, about turning towards the possibility of failure. The critics of goalsetting are effectively proposing a new attitude towards failure, too, since an improvisational, trial-and-error approach necessarily entails being frequently willing to fail. The spiritual ruminations of Eckhart Tolle and Alan Watts, meanwhile, point to an even deeper kind of failure: the ultimate – and ultimately liberating – failure of the ego’s efforts to maintain its separation and security.
