How did you get to doing what you do?

This email is typical of the numerous questions people have shared with me. In the past year, I've come to realize that there are many people who want to change their existing jobs and move into this field. There are also numerous people completing undergraduate or graduate degrees, who are wondering what they might do next in this growing area of interest. In addition, there are also many people who would like more education in this area, but are wondering what that means.
