I'm a CNJ now and I'm going to start on goldsmithing as soon as I can complete the instanced level 10 cnj guild quest. Goldsmithing was pretty lucrative in FFXI, and some of the jewelry items in this game seem pretty useful, plus there're a lot of jewelry slots. Might get into mining as well, as that could supplement GS very well.
