Generally speaking, all humans worry about things they can’t control that are threats to survival. (Spoiler: Which is everything.) It takes discipline, mindset, and narration to overcome this.
We all worry about extending our life. Not to live forever, of course, but we don’t feel like we have enough time.
This is why we focus on legacy, impact, generosity, and how to make ideas spread. Because those things live in the ether. There is no expiration date.
Even today, we don’t know who invented the wheel, but we all appreciate it and recognize its impact.
