Sd: Sorry to say, but your daughter needs a reality check. And you too. So she never learned speech-writing. Does she have any writing know-how? Didn�t she have any school writing assignments, creative writings, essays etc? No cookie-cutter skills are needed. Adaptation is key here and in life.
So I suggest your daughter ask them what the speech criteria is, if she doesn�t have that info yet. She can call up last year�s valedictorian for suggestions if necessary, and roll up her sleeves. Once she�s more or less done, you can help her with the editing.
And get off your perch about making a speech that�ll be life changing for the girls. By having too high expectations, you�re probably freezing her out. Be realistic and it�ll come together better than expected. Hatzlacha!
