The sequence is a bit odd, but the context of the words are the same I have used many times. I have heard others use them many times. Tell me your path to success? How will you go about achieving your life's goals? There are not that many ways and words you can use to ask someone where they want to be eventually. How are you going to get there?
Answer will contain: education, hard work, get along with others, integrity in dealings with others, honor their request, etc.
There are only so many words to use to explain your goals and plans to achieve. Even the words to expand a thought are fairly limited to words used previously.
Assuming Mrs Trump actually wrote her own speech, I doubt she had interest in politics in 2009 to even listen to Mrs Obama speech. She may have done some research on prior speeches, but I doubt that she was careless enough to copy word for word her predecessor.
Other than "the first time in my life, I have been proud...... " speech was the only time I remember anything she said worth repeating. Really, how difficult would it have been to recall words and order in a speech 7.5 years ago, and compare to something last night? What would be the degree of difficulty to distinguish those words as being part of Mrs Obama's speech so long ago? I have heard the same words used by so many others at different times that it would have been near impossible to determine who used the words in near same order.
