You would need to work. There's any number of jobs here - some run by locals, others created and run by foreigners like ourselves.

I work for the Vatheon Defense Force, as a sentry leader for the Carnival Quadrant and a trainer. There's also no restriction on how many jobs one can hold, so long as they're not exhausting themselves. The coral does help with a certain level of rejuvenation, but if you're working yourself nonstop it's likely you'll wear yourself out before you ever make it there.
