The same details that make foreign travel so confusing – Do I tip the waiter? Where is this train taking me? – turn out to have a lasting impact, making us more creative because we’re less insular. We’re reminded of all that we don’t know, which is nearly everything; we’re surprised by the constant stream of surprises. Even in this globalised age, slouching toward similarity, we can still marvel at all the earthly things that weren’t included in the Lonely Planet guidebook and that certainly don’t exist back home.
….We travel because we need to, because distance and difference are the secret tonic of creativity. When we get home, home is still the same. But something in our mind has been changed, and that changes everything.
— from Imagine by Jonah Lehrer
