I turned a few things at school when i was 14-15, really enjoyed it, but unfortunately the teacher didnt understand the basics of turning tool sharpening and would not let us regularly sharpen the high carbon steel tools they had. This meant turning with blunt tools, and lots of sanding. Despite this I really liked it.
I bought my first lathe at 17 in the late 80's, it was a really old belt driven lathe with step down gearing and tool holder for metal turning. I continued the falsehood of using blunt tools for a while. Had to learn for myself the errors I had been shown, and correct them.
Have gradually improved over the years, got books, bigger & better equipment, and practiced a lot over the years. Still think that one of the things that really helped me was to grind/sharpen by hand, rather than rely on jigs. I had to learn the angles when hand holding the tools otherwise I would have multi faceted tools, which in turn meant that when on the lathe i knew the angles.
My Dad bought a lathe a few years after i got mine, he took another route to learn the basics, and I believe was the first person that Nick Agar (when he was at Dartington) taught to turn. Nothing like learning from one of the best!
