@GinevraCat when I'm especially burned out, I'll do the pomodoro technique for 25 mins with a 5 min break. Rinse and repeat. After a few cycles, I somehow calm down my unquiet mind.

I show the timer on my phone so that if I try pick it up, I see the timer and put it down again. Then I try get up during the break and get water or something rather than pick up my phone
