Resist these forces.
Even as a medical student, I've thought of Harrison's Principles of Internal Medicine as the best textbook we've had: well-written, organized, and funny. Have you read the Hematology chapters? A riot! I'm so glad Harrison's also main reference material for residency. I enjoyed reading much of it. There's no virtue in it from me (a phrase I'm adapting from Dr. Albert Mohler): I just like to read. I'm the type who learns a lot more from reading rather than doing or listening.
I was re-reading Oncology and stopped for a minute when I encountered the paragraph above—never have I encountered textbook medical writing so humane and emphatic.
