Entering graduate students should make it their mission in a PhD program, therefore, to discover a type of research that they love doing. Look for journal articles that you think make more fascinating reading than the best novels. Look for articles and research presentations that have you shaking your head and saying, “Wow! I wish I had run those studies!” Look for research programs that get you so exited you cannot stop thinking about related concepts and cannot wait to get in the lab to test the latest ideas.
