I learned C without too much difficulty as a teenager, and also began to learn C++ at that point (I doubt anyone ever finishes learning C++), but I abandoned Win32 and MFC in disgust when I briefly tried to learn them at age 18 in the late 90s. Maybe I would have gotten further if I had started younger, or if I hadn't been spoiled by Java first. As it happened, I didn't really master Windows programming until my 20s when I had to do so for a paid job.
