We all must maintain generous margins of safety in everything we do and it’s important to keep them flexible.  The variables include altitude, speed, bank angles, escape options, the performance  and handling characteristics of your aircraft, prevailing weather, and potential turbulence.  Be honest with yourself – other pilot’s margins may not suit your needs.  Always have this moment’s margin foremost in mind, and if you inadvertently exceed it without getting hurt see that as an undeserved lucky break, not something to be repeated.  YOUR LIFE COULD DEPEND ON THIS!
