Theme of Speech: Life and Career

Ellen's speech, as you might expect, has its humorous moments. But it also explores some of the very personal and tragic episodes in her life that helped push her into comedy in the first place. Two key themes of DeGeneres'speech: overcoming adversity and being true to yourself. ForDeGeneres, that meant pushing onward with her career after her sitcom was canceled in response to her publicly coming out as gay.
