In 1984, a health teacher at the high school told me I would never amount to anything. And more than once. I considered it a form of verbal abuse. There was no doubt I was wild, immature and a bad student. But, on the other hand, I was creative as hell and back then, conservative high schools often didn't have an answer for students like me!
Years later, I went back to the school, found this teacher and showed him my W2. "Does this look like someone who didn't amount to anything?" He chuckled and said he didn't remember who I was. I told him it was difficult not to remember who HE was and I told him how hurtful those words were and that I hoped he was no longer saying such damaging dreck to his current students.
