When I was at school my inspiration was to do well rather than to head for a career in Engineering so I always tried to work hard and not be too naughty!!
They say you never forget a good teacher and I was fortunate to have some good ones. I had a German teacher called Mr Spaull and he used to turn the lights off if people were getting boisterous and it calmed everyone down straight away (it was inspired) . He then would turn them back on and say “now were back from the dark ages, lets do some work”.
I also had some great science teachers and they fired a passion of science and learning in me. There was an incident with a bunsen burner, some tongs and a pupil’s ear that still haunts me. Everyone in that class learned about heat transfer that day and will never ever forget it.
*disclaimer* Please do not mess about in science and listen to your teacher.
