As someone who has changed jobs several times during my (admittedly brief) career, I can attest that this is good advice. Keeping a portfolio of work, and a way for other people to judge your skills, is key. This can be as simple as a github account with some throwaway projects that show off your coding style + preferred languages/frameworks, or your own website, with custom wordpress theme, interactive portfolio work, etc. It's a little scary to jump into something new, but you'll be challenged again, and given an opportunity to work with people that will appreciate and (more importantly) understand what you do.
