I agree with you to some extent, josterD. But I think many more people have the raw capability to learn how to use the tools and techniques than would have the interest or the creative impulse to do anything meaningful with them.

Interest is the primary motivator for learning. With no interest in a subject, no-one is ever likely to learn much about it. I recall two long years at school grappling with Pure Mathematics, which bored me silly back then. Applied Mathematics, on the other hand, I could do standing on my head, simply because it sparked my interest.

I think the thing that is not so easy to teach/learn is the creative impulse... the mindset of imagining something, or seeing something in the world, or perhaps in others' artistic work, that inspires creativity in oneself.
