Let me tell you about my experience with teachers. In 6th grade I was blessed with a great one. She loved my writing and despite being a very unpopular kid in school she offered me up for a special creative writing class. I got in there and mingled upon jocks, the popular and the unpopular. it changed my view on my abilities but I still was so unsure of myself.
The next year I had an English teacher who demanded we participate in class and made it mandatory that we entered our writing in a local juco's literary review. The 3rd day of class, sitting silent as a stump, she called me into the hall. I was astonished and amazed. I had done nothing wrong.
When I got there, she said (and I will never forget this), " do you think I am better than you?" Of course I said yes, after all she was the teacher. Then she proceeded to tell me that her words were formed by her brain just as my words were formed by mine. She would make me express myself, hell or high water, and I'd best take the easy way out and jump in or she would make it her sole purpose to include me if that meant me giving a report every day at the beginning of class. Initially the fear of the worst prompted me. Eventually the confidence of what I am motivated me.
To say a teacher isn't worth anything is a shame in my mind. They shape the most important aspect of our world--Our future.
