For me, I am driven by two main philosophies: know more today about the world than I knew yesterday and lessen the suffering of others. You'd be surprised how far that gets you.
I lose sleep at night wondering whether we are intelligent enough to figure out the universe. I don't know.
I think the greatest of people that have ever been in society, they were never versions of someone else. They were themselves.
One of my great laments is that education today seems to have... be less about passion and more about process, more about tactic or technique.
Passion is what gets you through the hardest times that might otherwise make strong men weak, or make you give up.
People who are scientists today are scientists in spite of the system, typically, not because of it.
