I have been many things to many people in many places over my long life. I have come to realize I am nothing and no one. My last several career years centered on developing practical, planetary scaled, technical solutions suitable for climate change mitigation.
Finally a quote I live by:
“Whoever fights monsters should see to it that in the process he does not become a monster. And if you gaze long enough into an abyss, the abyss will gaze back into you.”
― Friedrich Nietzsche
