Not just from the room you’re standing in right now, but from your current situation. Know how to extract yourself from a busybody, a toxic relationship, an insensitive friend, and that one guy you were mistakenly nice to that won’t go away.
Know how to change a tire. Know the basic functions of engine parts. Do not rely on the kindness of strangers, friends or family.
Know how to leave a job that no longer fits you. Know how to leave any relationship that no longer fits you.
Shake yourself awake and look around. Do not let rote activity lull you.
Stop and think. If there was an active shooter in my location, where would I go? What would I do?

TL;DR: Know your escape routes in life and use them as needed. Don’t become too complacent, that would be a Rook mistake.
