I feel fear quite strongly, but when something is important enough, I believe in it enough to act despite the fear.

It's normal to feel fear; you shouldn't let fear stop you from doing something important.

Accepting the probabilities can diminish fear; I thought the odds of success with SpaceX were less than 10%, but I accepted that risk.

Even if I might lose everything with SpaceX, I believed we could still make progress and that another company could continue the work if we failed.

With Tesla, I thought the odds of the company succeeding were extremely low, but I still pursued it.
