It's only 180 days
You may teach English 11 for 25 years. You may have read The Great Gatsby 20 times. You may have written or read 1000 papers on Death of a Salesman . But those kids in front of you, (at least the vast majority of them), they only have 180 days of English 11 with you. It's the first time, the last time, and not a moment to spare.
