It depends on the passion as well. Not all passions are equal and can be easily transferred into a successful career. Assuming you have multiple passions, my personal advice would be to maximize money/time ratio for your career that corroborate with one of your passions to have some job satisfaction as well as pursuing your other passions.
For example, if you have a passion for say writing and computer science, I would recommend to get a job in CS, since money/time ratio is usually higher there.
