Jonah Lehrer on travel as a basic human desire that makes you smarter, more open-minded, and creative:
When we escape from the place we spend most of our time, the mind is suddenly made aware of all those errant ideas we’d suppressed. We start thinking about obscure possibilities … that never would have occurred to us if we’d stayed back on the farm. Furthermore, this more relaxed sort of cognition comes with practical advantages, especially when we’re trying to solve difficult problems.
[S]easoned travellers are alive to ambiguity, more willing to realise that there are different (and equally valid) ways of interpreting the world. This in turn allows them to expand the circumference of their “cognitive inputs”, as they refuse to settle for their first answers and initial guesses.
Even though we most often need a holiday after our holiday, it was worth it in the first place to get to the last place.
