There is this song that I like by Jackie Greene with a refrain in it that repeats “Oh, it’s just as well.” I think we should all be so lucky to have that be the chorus line after each event in our own lives. That our reaction to each occurrence is agnostic.
Marcus called it the Art of Acquiescence. Lincoln thought it that it was the one truly appropriate response for all situations. But this is too often misconstrued as “accepting” bad things that happen to you. Really the least important and easily accomplished half.
The idea is to take both the bad and the good equally, in stride. The subtle but critical difference between resilience and robustness is that resilience is about withstanding pressure while robustness – that is: vigor, strength, health – is the ability to withstand change.
