Is there a legitimate career that involves traveling and writing about it, or do those who do it simply have a lot of wealth and free time?

Yes, there are legitimate careers that involve traveling and writing about it. One such career is travel writing, where the writer travels to different places, experiences the culture, and writes about it for publications such as travel magazines, newspapers, and blogs. Another career option is a travel photographer, where the person travels to different places and takes photographs to be used in travel publications. There are also careers in the tourism industry such as tour guides, travel agents, and travel bloggers who get to travel as part of their job. While having a lot of wealth and free time can make traveling easier, it's not a requirement for a career in travel writing or photography. These jobs typically require a lot of hard work, perseverance, and a passion for exploring new places.
