Men’s counselor and author Wayne Levine calls boundaries N.U.Ts, or Non-negotiable, Unalterable Terms. Your N.U.Ts are the things you’re committed to: your family, your health, your faith, your hobbies, your psychological well-being, etc. According to Levine, “N.U.T.s are the boundaries that define you as man, those things which, if repeatedly compromised, will gradually—but assuredly—turn you into a pissed-off, resentful man.”
