I don't fully understand how he did it. I know he took a lot from the line in the Talmud that said "whoever saves a life, it is considered as if he saved an entire world."

My mom says that his baseline was incredibly high and that he was incredibly resilient. He also had a big rebellious streak, an analytical mind, and endless compassion.

I am not Jewish but I learned about this phrase watching the film Schindler's List in high school. That phrase, and listening to Ben Kingsley's character say it, has lived, rent-free, in my mind for the last umpteen years.

My father knew a neurosurgeon in the 70s(?), when the outcome statistics were pretty bleak.

He asked him how he handled it, and the guy said "Because the few that I save wouldn't be, if we didn't do anything."

Sometimes, greater than zero is the win.
