Right now I'm reading a book called "Time, Love, Memory" (by Jonathan Weiner) for class. It's the story of Seymour Benzer, a pioneer of fruit fly behavioral genetics. He had worked for 10 years on a particular gene, and was mentally going through the motions. His former mentor, Max Delbruck, realized this and added a postscript to a letter from Delbruck's wife to Benzer's:
"Dear Dotty, please tell Seymour to stop writing so many papers. If I gave them the attention his papers used to deserve, they would take all my time. If he must continue, tell him to... underline what is important."
Scientists have the best quotes!
