I'd be interested to know, too. I interpret that statement, personally, to be more along the lines of "maintaining my employability (in this industry)." Maybe upbringing / background plays a significant factor here? I watched both of my parents very unceremoniously lose their job-for-life jobs and nearly everything along with it. My primary motivation, then, to stay abreast of the industry, to pursue new skills/technologies/challenges, things that I would put under the label of "opportunities for professional growth," has (not entirely, but for the most part) little to do with the amount that I'm paid (considering that I perceive myself to be paid well) and everything to do with maintaining a recurring paycheck until I'm retirement age.
