So do most people. When you're young, you can work for a tour company, either in the office or in the field. But if you work in the field, you'll need to be fluent in at least one foreign language. You'll also need to be patient, very organized, flexible, and forceful. It's not all romantic. It mostly involves logistics.
There used to be a career field as a travel agent, but with the internet, that disappeared. You can consider working for the federal government, but that isn't very romantic, either. If you are in the foreign service, you can start at low level jobs in embassies, consulates, and with cultural attaches.
You could get a PhD and become an academic and teach and/or do research. But beware: universities have a tenure system and there tend to be ebbs and floes of hiring. I didn't finish my PhD because there were no jobs. There had been a wave of hiring several years before and aspirants had to wait until these people retired, died, or weren't granted tenure.
This is a bit of a romantic goal: like being a movie star. Try to think about what it is about traveling and experiencing other cultures and then try to find a job that may be in another field that encompasses those. For example, you might find that you enjoy teaching elementary school in a multi-cultural environment or social work with people from different backgrounds.
