At primary school I was strong in mathematics.
Later, I progressively lost interest for scientifical topics and focused on humanities.
Of course, the teachers at secondary level were not very inspiring, but it is also true that I found difficult (and still do) understanding formulas and abstract theories.
Actually, the same apply for philosophical or artistic theories. I tend to shy away from more complex reasoning; not sure if that is for laziness or structural limits.
Also, I am not particularly ambitious.
I wondered sometimes where I would be if I had pursued one determined purpose with everything I had got.
Probably, in the same place.
