When I began work on my first book, The River of Doubt, which tells the story of Theodore Roosevelts 1914 descent of an unmapped river in the Amazon rainforest, I thought of it as a tale of adventure, exploration and extraordinary courage.
What I saw wasn't a ghost. It was simply--myself. I can never forget how terrified I was that night, and whenever I remember it, this thought always springs to mind: that the most frightening thing in the world is our own self. What do you think?
