Here's another point, and this pertains to car model builders in particular. You develop your tastes whether you like it or not by cutting your teeth on styrene. It seems to me you are not going to build what you don't like, right? Why waste precious time building yet another box stock or whatever if you don't like it . . . the same is true for the vehicles and styles you don't like.
One of my great disappointments when I went to build my first Nascar (I built it for a friend's mother for a birthday gift) was that all those kits are the same . . . of course, I don't know anything about Nascar but it dawned on me that the parts that came in the kits were really limited, and I felt I lacked all the skills to be able to produce a good model, so I naturally blamed the kit and not my skills at that time . . . anyway, it turned me off from trying to build Nascar, but it doesn't mean I don't respect a well built Nascar model.
As a matter of fact, I would say that your limitations as a builder are exactly the attributes you end up respecting in someone elses' work.
