Query: Statistical Model Building, Machine Learning, and the Ah-Ha Moment   The Committee of Presidents of Statistical Societies (COPSS) will celebrate
its 50th Anniversary in 2013. As part of its celebration, COPSS intends to
publish a book with contributions from the past recipients of its four awards,
namely the Fisher Lecture Award, the President's Award, the Elizabeth Scott
Award, and the FN David Award. The theme of the book is Past, Present and
Future of Statistical Science. As a winner of the Elizabeth Scott Award, I have
been invited to contribute. We were given several topics to choose from and I
have chosen to focus on "Statistical Career: Your reflection on your own
career, lessons and experience you have learned, and advice you would like to
provide to young statisticians if sought." This article is my contribution.
