Certainly there will be situations that make you disengage, and that is where we have the choice of what we want to be. The best version of yourself! good phrase.
The uncomfortable, destabilizing moments will always be there, I think, in the work environment, although also in the secular. But the point is, what will we choose to be at that moment? I think it is important to stop before answering and yes, that is where the expression you mentioned should come from, to be the best version of oneself! ,why let out that which we know will not contribute at all to good relationships or peace ?

Good saying @galenkp
