I can't remember a single time [my parents] ever told me not to do something I wanted to do.
I didn't really decide that I wanted to be an astronaut for sure until the end of college.
I have been a bit of a risk-taker all my life.
You know, I go around the country a lot.
I did not come to NASA to make history.
Ever been to Disneyland? That was definitely an E ticket!
