Still, if man does not live on bread alone, I will contend that we should not limit our reading to the narrow focus of our chosen profession(s). I have learned much from a wide range of reading that, coincidentally, positively informs my work on a day to basis and it comes in all forms and all manner of surprising ways. I encourage a well rounded reading life - find your own surprises and share them with friends and colleagues.
I am just finishing Rampersad's 2 volume biography of Langston Hughes and it is something to near the end of the work and the end of Hughes' life. He was a decent and dignified man who gave us some great poetry, filled with the humanity he saw around him and made manifest in his own life.
I am in the middle of E.O. Wilson's The Social Conquest of the Earth and I just started The Swerve: How the World Became Modern by Stephen Greenblatt. More on these as I finish.
Finally - one more plug for Kahneman's Thinking, Fast & Slow - this will help you in your professional and personal life - incredible insight into the workings of the human mind.
