I loved the travel but I didn't love the work. I mean, come on, modelling is only so stimulating!
Well, the whole story is in the book, but the short answer is that I was the first information architect in an organization that was traditionally design-oriented, and I felt I needed a tool to help me gain the trust and support of my colleagues.
I have written a memoir here and there, and that takes its own form of selfishness and courage. However, generally speaking, I have no interest in writing about my own life or intruding in the privacy of those around me.
