At first sight this makes sense - in its truest meaning. And poses some questions: Do we really thank our teachers? At school? At college? The university? At our first job? In live?
Do we know, when - and what - we learn?
Do we accept to learn? Do we enjoy learning? Do we appreciate to learn, to be taught? To develop? To outgrow ourselves?
At second thought I asked myself: what might be the best way to thank your teacher!? How to really value what she has done? How to value the time he spent with you, discussed, argued, and learned together with you? How to value all the thoughts and sorrows she went trough to develop you, to help you grow.
There is only one answer:
You yourself should teach others by further developing what your teacher has tought you! Value what s/he has done (and is doing everyday) for you by spreading the word yourself, by helping others, by inspiring others like your teacher does.
11:48 hrs > Seth shows that you may even "... learn from a lousy teacher...".
Might be true that we even should thank a lousy teacher. He just makes us stronger. - But I think that's only right for the ones that are strong already.
Seth's 7th and additional point should be: Inspire the lousy teacher to outgrow himself by following YOUR example!
