… excellence is not a law of physics. Excellence is a moral act.~ Huch MacLeod from, https://www.gapingvoid.com/blog/2020/02/03/why-excellence-is-a-moral-act/
You create excellence by deciding to do so, nothing more. It doesn’t matter if you went to the wrong school, or were born on the wrong side of the tracks, or working the wrong job.
You go into the situation and you go the extra mile. Your decision. You own it. You own the potential downsides as well.
