Traveling the world a little bit at a time can offer life experience that no amount of internet research can bring, because you are not only seeing the world, you’re getting the opportunity to taste, smell, touch, and live in the moment.
Good writing always puts the reader right into the moment, into the location, and life experience makes a writer more capable of describing the world in a way that the reader can almost experience it themselves. To do that, it’s important that you first experience life fully. And what better way to do that than through travel?
