i believe it's Leah Lakshmi Piepzna-Samarasinha's book Future Is Disabled that talks the most about time/speed/rest like this, from what i remember. it's really lovely! and 100% agree regarding the exhausting expectation of immediacy. i'm working prioritizing my energy, too! easier said than done. :) this also makes me think of a video i saw on instagram a while back where the poster said they were trying to focus less on how productive/efficient they could be while completing a task, and focus instead on how physically and mentally relaxed they could feel while working.
wow that's so kind of you, i really appreciate that!
