No desire to travel outside home country means no passport required

I can understand that. It's perfectly fine, just traveling within the country, usually it's large enough and there're so many places to discover... Plus you can easily communicate knowing the language, that's a big thing you know, you can more easily make friends like that... But nothing can compare with traveling to a country you know nothing about. Stepping out of your comfort zone, and as the cliché has it, cure your racism, understanding of the world.... nothing can truly teach you how we are all humans, despite our differences, like traveling abroad. So there're benefits in every situation:))
