Listening non-technical audio books seems to be one of the most effective ways to get my mind off work late at night, and not to dream about programs and bugs during sleep.
I’ve enjoyed The Audacity of Hope by Barrack Obama. Perhaps because he was once a professor, the intellectual depths and rigor exhibited in this book far exceed Bill Clinton’s My Life and Hillary’s Living History. One interesting observation is that he derived a lot of his reasoning and understanding from the frame of constitution. That is something I plan to study one day.
