Do we really want to travel in hermetically sealed popemobiles through the rural provinces of France, Mexico and the Far East, eating only in Hard Rock Cafes and McDonalds? Or do we want to eat without fear, tearing into the local stew, the humble taqueria's mystery meat, the sincerely offered gift of a lightly grilled fish head? I know what I want. I want it all. I want to try everything once.

Glasgow is maybe the most bullshit-free place on earth. I think I call it "the antidote to the rest of the world." It's so unapologetically working class and attitude-free. Everyone's looking "to take the piss out of you," as they put it. They're all comedians, and tough. They don't put on airs.

It seems that the more places I see and experience, the bigger I realize the world to be. The more I become aware of, the more I realize how relatively little I know of it, how many places I have still to go, how much more there is to learn. Maybe that’s enlightenment enough - to know that there is no final resting place of the mind, no moment of smug clarity. Perhaps wisdom, at least for me, means realizing how small I am, and unwise, and how far I have yet to go.

If you’re twenty-two, physically fit, hungry to learn and be better, I urge you to travel – as far and as widely as possible. Sleep on floors if you have to. Find out how other people live and eat and cook. Learn from them – wherever you go.

If I'm an advocate for anything, it's to move. As far as you can, as much as you can. Across the ocean, or simply across the river. The extent to which you can walk in someone else's shoes or at least eat their food, it's a plus for everybody.Open your mind, get up off the couch, move.

The journey is part of the experience - an expression of the seriousness of one's intent. One doesn't take the A train to Mecca.

It’s an irritating reality that many places and events defy description. Angkor Wat and Machu Picchu, for instance, seem to demand silence, like a love affair you can never talk about. For a while after,you fumble for words, trying vainly to assemble a private narrative, an explanation, a comfortable way to frame where you’ve been and whats happened. In the end, you’re just happy you were there- with your eyes open- and lived to see it.

Looking at these photographs, I know that I will never understand the world I live in or fully know the places I've been. I've learned for sure only what I don't know - and how much I have to learn.
