This is really really good advice for so many reasons. First of all, you never know when you'll lose your medical or you'll get furloughed. You also are going to be spending your life with pilots so the fact that you're a pilot isn't interesting. So many guys who have gone directly from the aviation degree to the airlines are a little boring because they don't really have much to talk about outside of airplanes because it's all they know. Broaden your horizons -- you're young and you've got plenty of time to get into the industry.
