That boring activities become, perversely, much less boring if you concentrate intently on them. That if enough people in a silent room are drinking coffee it is possible to make out the sound of steam coming off the coffee. That sometimes human beings have to just sit in one place and, like, hurt. That you will become way less concerned with what other people think of you when you realize how seldom they do. That there is such a thing as raw, unalloyed, agendaless kindness. That it is possible to fall asleep during an anxiety attack.

That concentrating intently on anything is very hard work.
