For a civilisation so fixated on achieving happiness, we seem remarkably incompetent at the task. - Oliver Burkeman

Perfectionism is the voice of the oppressor, the enemy of the people,' the infinitely more sensible essayist Anne Lamott observes in her book on writing, Bird by Bird. 'It will keep you cramped and insane your whole life … perfectionism is based on the obsessive belief that if you run carefully enough, hitting each stepping stone just right, you won't have to die. The truth is that you will die anyway and that a lot of people who aren't even looking at their feet are going to do a whole lot better than you, and have a lot more fun while they're doing it.

the more you focus on using time well, the more each day begins to feel like something you have to get through, en route to some calmer, better, more fulfilling point in the future, which never actually arrives.

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.
