The real lesson, is that it pays to use whatever freedom you do have over your schedule not to 'maximize your time' or 'optimize your day', in some vague way, but specifically to ring-fence three or four hours of undisturbed focus (ideally when your energy levels are highest).
The capacity to tolerate minor discomfort is a superpower. It’s shocking to realise how readily we set aside even our greatest ambitions in life, merely to avoid easily tolerable levels of unpleasantness. You already know it won’t kill you to endure the mild agitation of getting back to work on an important creative project; initiating a difficult conversation with a colleague; asking someone out; or checking your bank balance – but you can waste years in avoidance nonetheless. (This is how social media platforms flourish: by providing an instantly available, compelling place to go at the first hint of unease.) It’s possible, instead, to make a game of gradually increasing your capacity for discomfort, like weight training at the gym. When you expect that an action will be accompanied by feelings of irritability, anxiety or boredom, it’s usually possible to let that feeling arise and fade, while doing the action anyway. The rewards come so quickly, in terms of what you’ll accomplish, that it soon becomes the more appealing way to live.
