Who wrote the foreword to three cups of tea?

The foreword to "Three Cups of Tea" was written by Greg Mortenson.

While it may seem surprising that the author of a book would also write the foreword, it is common for authors to offer their perspective on the book and its genesis. In this case, Mortenson likely wanted to use the foreword to highlight the personal journey that led him to write the book and the impact it had on his life.
