Ultimately, travelling is all about getting to know yourself
There have been plenty of times when I have faced a crisis, and a degree of emotion that surprises even me has welled up, driving me into action to overcome the crisis. Sometimes I scream and cry on my own, it's too tough, it's too hard, I want to give up and go home, I'm lonely - but even so, I've always just kept on going. The reason I keep travelling is because the feeling is so strong that I want to find the part of me that even I don't know. Also, travelling makes me think of all sorts of things.
