This can't be understated, and I'm glad you see that. Also, about the programming languages-- you may think you can program well in them, but you most certainly can't. By virtue of the the fact that knowing a syntax (or idioms) is far different from having domain knowledge, not to mention your age. The fact that you can type the correct syntax for those languages is irrelevant--You have no real-world knowledge about how this is used, which greatly impacts how you build software. That's one of the many reasons why young, "bright" developers will never surpass experienced developers-- it's more than "coding."
