"A person with a strong knowledge of "the basics" but with no ability to teach themselves never could succeed in a fast-changing profession, at least not without the help of others to continually teach them what they did not know. Conversely, a person knowing nothing but how to teach themselves could always learn what they needed to know in whatever profession they chose, with or without anyone else's assistance. Ergo, the ability to learn independently is more important than the mastery of specific knowledge areas."
