@nprofile1q... yeah I remember learning this for the first time as part of basic management strategy.
If you plan your future in a way that assumes you or your team gives 100% all the time, that means literally any disruption will bring cascading larger disruptions and delays.
Your "best" should be restorative and sustainable - your "emergency capacity" is an entirely different thing. If your environment makes you feel/expects you to act like you're in an emergency all the time, that's a problem that needs larger fixes.
