Ah, I wanted to add:
Like you, I also base my believes on personal experience.
I was pretty much excellent at all subjects at school, until I was about 14. My parents are both intelligent people, though I don't believe they have trained me in any way. They were too busy managing their own lives at the time. School did not teach me either, school has always bored the shit out of me. People who did not perform well got extra attention and help. I received praise, but no extra stimulation.. I never had to learn, practise, do my homework, ended up being allowed to come less hours to school when I was around 10 and spent that extra time talking about video games and attending social training.
My primary school class consisted mostly of children of immigrants, and was located in a disadvantaged neighborhood. Also I was among the younger people in my class. All those 3 things should give me a statistically smaller chance to perform well...
Still my IQ tests scored very high!
So, my believe is that this is mostly genetics, since I can't imagine what advantage I have in stimuli and training over others...
At age 14 I dropped out of school, I believe mostly because the lack of stimuli terribly ruined my curiosity. :(
