By the journey’s end, I will not be the man I am today. Africa will have changed me in ways I can't predict, perhaps in ways profound, perhaps only superficial, perhaps I will lose a few pounds, perhaps the arrogance in my walk, perhaps my walk, even my way of looking at things, will be a little more African. But for now, I am different. I am not one of these Africans. Not yet, and may not ever be. The color of my skin says that I could be
Algerian or Senegalese or from Chad. But the Tunisian eyes that watch me can see that I at least am not from Tunisia. They know I am not one of them, but they do not know where I come from.
The whole of Africa lies before me and I have no plan, no travel plan. It might be better if I were searching for some three-legged zebra, for at least I would know when I found it. Without a plan, without a goal, a traveler is at the mercy of the road. Traveling overland is not like traveling on a river. The river has a beginning. It has an end. The path, though not straight, is defined. Not so traveling overland. The prospects (前景)，like the possibilities and promises of life, are endless and varied.
An old man asks, “Where in Tunisia do you want to go?”
I have no idea. It isn’t always the getting there that is important. Sometimes it’s just the going. “Go to Sousse.” he tells me. “Go to Sfax.”
