Once upon a time indulged in a 20-plus-year "first" career as software developer and consultant, mostly working in C, unix, SQL, IVR, CTI, and for the grand finale, Cocoa and Objective-C. Now on my "third" career as aviation instructor at a college by day and self-employed Mac developer by night. (Details about my "second" career come with coffee or beer.) Currently authoring an app on my own for the education sector to debut in the Mac App Store... one of these days.
