From my perspective, I can add some thoughts to the "learning curve" point. The primitive sketches I put on computer paper at age 5 are almost laughable, and I would say that nothing I drew was really any good until high school. Even those had way too much modern/major championship influence though. It wasn't until the end of high school and start of college that I really started to know what I liked and what I wanted to do. Since that sort of epiphany, it has still been a constantly evolving refinement of those new-found ideals, and I am convinced that the evolution will never stop, as you can always learn more and strive for more in this line of design. I have already spent 20+ years learning what I like and want to do, and who knows how many more before I get my chance to put it all into the ground, but I am sure that when I do, the learning will be amplified to yet another level. I think that is realistic and not a bad thing at all.
There is just way too much to learn and understand in golf architecture to be a prodigy from birth, and I am not even talking about the business side, ROI, construction management, permitting, client input, agronomy, etc.
