How does travel become a profession?

Speaking of which, I've thought about it. If we always travel, people can make money. Later, I thought there were several kinds.

Tourism is a high-investment occupation, because I think the most profitable thing is to travel with a group, or you can join a travel agency or open one yourself, and you can travel with a group every holiday. At this time, it is best to go to distant places, such as Tibet, Lijiang, Nansha and Harbin. And organize a collective bonfire party on the grassland in Inner Mongolia. But all this requires that you have been to these places. You can't be a traveler. When traveling, you should pay attention to local customs, the route of reciting place names, familiar hotels, etc. Especially the hotel commission is also very rich. In fact, it is a disguised tour guide, but it is relatively free. Besides, you are very famous in the circle. In China, many rich people like to travel, such as climbing Mount Everest. In these places, they may stop after climbing hundreds of meters, but they need to hire people who are familiar with the survival of the wild plateau, which is also a way to make money. There are also several famous people who go far away on foot or by car, and some people sponsor publicity and so on. This profession is very free, but I don't think single people will make any progress without running a travel agency. Moreover, it will burn a lot of money in the early stage, which will not be particularly stable and will not earn a lot.
