Every year on the first day of school I have students write about the following JK Rowling quote:
Some failure in life is inevitable. It is impossible to live without failing at something. Unless you live so cautiously that you might as well not have lived at all -- in which case, you fail by default.
My favorite response of the day was, " When my friends fail, I'm [going to] say 'I'm sorry and congratulations.'" What an insightful response! That might be my pep talk for students who encounter stumbling blocks in their learning this year. What a great tag line to remind kids that failure, while frustrating, is just a building block to success.
