I have been a bit of a risk taker all my life, not always in the traditional way of defining risks, but when I was growing up, it was probably risky for a young girl to decide to be a scientist. It was probably, even when I was in college, risky for a female college graduate to go on to graduate school in physics, and certainly going on to be an astronaut was taking a risk. But I think that it is important to be willing to take that step, to kind of make that leap to do what you want to do, and that is my definition of being a risk taker.
