3d modelling is more about "thinking 3d" and knowing how your tool works. Also you need a lot of practice. Talent is also a nice to have
During my 9th to 13th grade I was hobby modelling with Cinema 4D. I even wrote a research paper about the basics of 3d modelling with Cinema 4D while a friend of mine wrote one about 3d animation with Cinema 4D. In the next year our teacher organized licenses for a new course called "electronic publishing" where we (my friend and I) "teached" our classmates on how to work with Cinema 4D.
