Many things are improbable, only a few are impossible.

I tend to approach things from a physics framework. And physics teaches you to reason from first principles rather than by analogy.

I would like to die on Mars. Just not on impact.

Failure is an option here. If things are not failing, you are not innovating enough.

I wouldn't say I have a lack of fear. In fact, I'd like my fear emotion to be less because it's very distracting and fries my nervous system.

It was obvious to me that we could never colonize Mars without reusability, any more than America would have been colonized if they had to burn the ships after every trip.

I think it's important to reason from first principles rather than by analogy. The normal way we conduct our lives is we reason by analogy. [With analogy] we are doing this because it's like something else that was done, or it is like what other people are doing. [With first principles] you boil things down to the most fundamental truths…and then reason up from there.
