Following mike’s question, I thought this would be interesting to know.
As for me, From being a purely functional marketing guy that was marketing technology education and technology services unable to relate to the techies / electronics (i didn’t even know the difference between a processor/controller, between arm, avr & pic! lol), now being confidently able to understand, demonstrate and offer prototypes to the same techies on ideas that can sell. Add to it the joy of being able to introduce over 300 students to arduino and kind of enable them to explore further(however, sadly, only a fraction of them seem to stick on to anything they learn beyond their first project!) Its just been wonderful! A big change.
