Traveling can be one of the most intense learning experiences on the planet. Far more exhausting than the physical strain of ceaseless slogging through unfamiliar terrain is the overwhelming stream of mental stimuli, unfamiliar language and alien cultures.
Some travelers, myself included, opt to balance the heightened experience of a nomadic lifestyle with formal further education. Many universities now offer the option to move your studies off-campus, and there are even institutions dedicated to distance education. Open Universities Australia is a good example, but there are some less reputable operations as well so research is essential.
