Doris Kearns Goodwin: I think the most important preparation was, first of all, just loving it, loving to read history. Whatever it is that you do, if you have that passion and desire for it, that’s the most important thing. And then, what I tried to do all through college and graduate school was to go to Washington every summer, so that I could have an actual experience of government. I knew I was interested in American history and government, so I thought, instead of just reading about it I’d better find out about it in practical terms. So one summer I worked in the House of Representatives; another summer I worked in the Department of Health, Education and Welfare; and another summer I worked in the State Department. And then eventually I became a White House Fellow and worked for Lyndon Johnson. And that probably was the single most important experience in orienting me to want to do presidential history, because I got to know this crazy character when I was only 23 years old.
