Many songbirds migrate at night, when the air is calmer. Some of your best thinking needs the quiet hours too.

Conditions matter more than effort for certain kinds of work. Birds crossing at night are not braver than the daytime fliers, they are using calmer air, and your own difficult thinking has a similar requirement. The thought that needs room will not arrive in a corridor between lessons with notifications landing every forty seconds.

Find one genuinely quiet half hour this week, early morning or late evening, and bring the thing you have been avoiding thinking about. No music, no screen, no company. Treat the quiet as the equipment rather than the reward.
