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!
