Interesting. Not sure I agree. I like the directive but you're crossing industry growth (an economic term) with personal growth (a non-quantifiable, non-economic term). Personal growth may lead to economic growth, but lots of other things lead to economic growth as well. I like the idea behind the article, but only in so far as it spurs me to learn more. I don't think it stand up to rigorous analysis as a direct relationship between industry and personal growth.
