This might not be a direct answer , but reading " Peak: Secrets from the New Science of Expertise http://www.goodreads.com/book/show/29369213-peak" certainly helped nail down in my head that learning is a skill, and the only barrier to learning (and becoming an expert) and doing something is yourself and time (it explicitly says that you can't hope to be an expert by mindlessly repeating it or going through the motions though) . The book also lays down effective lessons for how to optimize for learning the skill fast (specifically with short iterational feedback loops) and effectively.

The book is fairly well researched, draws from credible academic sources and breaks down the "genius" construct fairly well. It left me knowing that any new subject or skill is approachable to anyone and everyone, as long as they are prepared to put in the time, and effort and an effective feedback loop in there.
