Cal Newport on Rituals
"To make the most out of your deep work sessions, build rituals of the same level of strictness and idiosyncrasy as the important thinkers mentioned previously. There's a good reason for this mimicry. Great minds like Caro and Darwin didn't deploy rituals to be weird; they did so because success in their work depended on their ability to go deep, again and again - there's no way to win a Pulitzer Prize or conceive a grand theory without pushing your brain to its limit. Their rituals minimized friction in this transition to depth, allowing them to go deep more easily and stay in the state longer. if they had instead waited for inspiration to strike before settling in to serious work, their accomplishments would likely have been greatly reduced."
