plans changed

During high school and my first year of college I was certain of my future plans. I intended to earn a biology degree and then enter a physician assistant program. Well, I'm currently a junior in a biology program and I no longer have that comforting certainty of knowing what grad program/occupation I should pursue after my days in college are over.

I have yet to find any occupation that would align with my interests and, at the same time, provide a definite and sufficient income. So, since I believe that the likelihood is rather low of determining in the next year what long-term career will work for me, I'm thinking of taking a year or two after graduation from college to do something that I won't do when (and if) I ever settle into a stable career. The only problem is that I don't know what to do.

Ideas I've considered include: working on a sheep farm in New Zealand or a Kibbutz in Israel, travelling through Europe, getting a job on a cruise ship, et al. A major consideration is that I need to find something that will provide an income or at least room and board since I don't have access to unlimited funds. Anyway, I thought I'd post this in case anybody has any helpful suggestions.
