ABSTRACT
Highly selected “ah-ha” moments from the beginning to the present of my research career are recalled — these are moments when the main idea just popped up instantaneously, sparking sequences of future research activity — almost all of these moments crucially involved discussions/interactions with others. Along with a description of these moments we give unsought advice to young statisticians. We conclude with remarks on issues relating to statistical model building/machine learning in the context of human subjects data.
