Children can't help but create: they need to put their mind on the page, they want to paint, to sculpt, to write short stories.
So let's not pretend that travel is always fun. We don't spend 10 hours lost in the Louvre because we like it, and the view from the top of Machu Picchu probably doesn't make up for the hassle of lost luggage. (More often than not, I need a holiday after my holiday.) 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.
