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

When we got Tesla going at the very beginning, if you asked me what I thought the odds of success were, I would have said less than 50%. I would have said that failure is the most likely outcome.

Mars is the only place in the solar system where it's possible for life to become multi-planetarian.

I just want to retire before I go senile because if I don't retire before I go senile, then I'll do more damage than good at that point.

Persistence is very important. You should not give up unless you are forced to give up.

You could power the entire United States with about 150 to 200 square kilometers of solar panels, the entire United States. Take a corner of Utah... there's not much going on there, I've been there. There's not even radio stations.

I've actually not read any books on time management.
