"The moment one definitely commits oneself, then providence moves too. All sorts of things occur to help one that would never otherwise occurred. A whole stream of events issues from the decision, raising in one's favor all manner of unforeseen incidents and meetings and material assistance which no man could have dreamed would have come his way. Whatever you can do or dream you can, begin it. Boldness has genius, power and magic in it. Begin it now." - Goethe
Years ago I adopted the motto "I live my life in direct proportion to the commitments I make and keep". That applies to my life...personal and professional. We seem to live in a throw-away world where we throw away people by disrespecting or ignoring them, throw away jobs as we run from what might be difficult, rather than learning from difficulty, run towards something we might think is easier, when it usually isn't and throw away things when they lose their novelty.
When we honour our commitments, we honour ourselves and those we've committed to. If for some reason the status quo has changed, then we still honour ourselves when, if need be, the commitments are redefined and not ignored or not thrown away.
For me, that's called authenticity.
But I'm not telling you anything you don't already know, am I?
