I think you have to be insane to not travel. The learning opportunities it presents are unparalleled.
The world would be a much better place if every person living in a developed country were forced to spend a year living in a different one during high school, for example.
Travel is fatal to prejudice, bigotry, and narrow-mindedness, and many of our people need it sorely on these accounts. Broad, wholesome, charitable views of men and things cannot be acquired by vegetating in one little corner of the earth all one's lifetime
- Mark Twain
