found a particularly resonant idea about travel. kent nerburg writes,

"that is why we need to travel- if we don't offer ourselves to the unknown, our senses dull. our world becomes small and we lose our sense of wonder. our eyes don't lift to the horizon, our ears don't hear the sounds around us. the edge is off our experience and we pass our days in a routine that is both comfortable and limiting. we wake up one day to find we have lost our dreams to protect our days."
