It's hard work. Sometimes you might imagine it as a dream life of a kind, but being away from ones you love is difficult. I try and take photos to remind myself of where I've been, and quite often I am not completely present at my destination. The images help fill in the gaps after I return home. The place becomes more vivid when it is reassembled in my memory at home from pictures.
I generally walk around lost and attempt to see things from a unstable point of view. Then I try and capture the feeling of looking at something as a first impression. Being lost comes easy to me though.
