I've been a college instructor and industry mentor for the last few decades. One thing I've learnt that there is volumes to be said about "peer learning". Sometimes it is more effective the closer the mentor and disciple are in capability. An expert may not even think about the little things, or dismiss them as obvious.
Aervax, you would be a great mentor!
As would anyone else on this forum!
Me? My star disciple is my 19 yo son. Unfortunately he doesn't listen much to me about academics. I'm closer to him in fishing, and we enjoy exploring and experimenting together.
