Circumstances are indeed important.
Parents, environment, disposition, siblings, nation/region/state/local, influences, the paths you choose, the paths you declined, the paths you ignored, what you felt was embarrassing, what you thought was cool, what you watched, how you spent your time, how much you listened versus how much you talked. How many great ideas and art crossed your path. The things your unique trajectory through time and space exposed you to.
Staggeringly random yet delightfully one’s own.
