Is there any way to make money while traveling?

You can find a job in the city you want to go to, such as working in an inn or cafe while traveling. After you have visited all the places you want to go, if you want to continue traveling, you can change to another city in this way. Moreover, you can make money by writing articles during your travels. You may not make money at first, but as long as you persist, you will certainly achieve it.
