“For the Stoics, the realisation that we can often choose not to be distressed by events, even if we can’t choose events themselves, is the foundation of tranquility. For the Buddhists, a willingness to observe the ‘inner weather’ of your thoughts and emotions is the key to understanding that they need not dictate your actions. Each of these is a different way of resisting the ‘irritable reaching’ after better circumstances or better thoughts and feelings. But negative capability need not involve embracing an ancient philosophical or religious tradition. It is also the skill you’re exhibiting when you move forward with a project – or with life – in the absence of sharply defined goals; when you dare to inspect your failures; when you stop trying to eliminate feelings of insecurity; or when you put aside ‘motivational’ techniques in favour of actually getting things done.”
