Many people are unhappy because there was some point in their past where there was some glory day, and as they get older they're not creating more glory days. They reflect on a time that they will never reach again, and it brings some level of dissatisfaction into their lives. I have circumvented that by simply making incumbent upon myself to always be productive in ways that are consistent with my physical body, my mental state of knowledge, but more important, my presumed growth in wisdom that would come with age.

Neil deGrasse TysonI want upon death to be buried, just like in the old days, where I decompose by the action of microorganisms, and I am dined upon by any form of creeping animal or root system that sees fit to do so.... I will have recycled back to the universe at least some of the energy that I have taken from it. And in so doing, at the conclusion of my scientific adventures, I will have come closer to the heavens than to Earth.
