In an interview with Reader's Digest, Mitt Romney named his campaign ("The Longest Journey"), invented a family saying (“This, too, shall pass") and revealed his favorite word: "Indomitable.") Interestingly, Romney used "indomitable" to describe New Jersey Gov. Chris Christie during an interview with Jay Leno in March. 

Romney also defined happiness -- "Happiness, for me, is a function of the number of people I love, and I think joy and happiness is directly related to how many people are in our lives and how deeply we are bonded with those people. And so I’m happy if I’m with Ann; I’m happier if I’m also with my family and my grandchildren."

And he explained how to deal with bad hair days: "If I have a bad hair day, I just think, Well, it will be an OK hair day tomorrow. Just put your head down and go."
