I'm a wanderer. Physically and mentally. I like moving about. In terms of direction and focus, I'm one of the worlds worst. I haven't yet found one thing in life worth studying to the nth degree for, or one profession worth earning money for. But that doesn't mean I wouldn't.
Meanwhile I'm going to see as much of the world as possible. That at least seems worthwhile. It's fairly cheap, it gives you perspective, it's adventurous, it's incredibly social and it's every human beings right to see as much of the planet as possible.
