I've read a couple of books lately that really spoke to me. It isn't so much that they educated me or really made me see things in a new way, but they better articulated things I'd been thinking about and hadn't necessarily put words to yet.
The first was Michael Lopp's Managing Humans: Biting and Humorous Tales of a Software Engineering Manager. This work took form from Lopp's Rands in Repose blog and his career. In this book he tells fabricated tales based on his experiences in the software industry. The experiences don't fall too far from my experiences, but the value of this book lies in creating terminology, and providing some tips, tricks and suggestions for given situations. For anyone who works with or in a high-functioning team, this book will provide insight into the people and systems involved.
The second is Randy Komisar's The Monk and the Riddle : The Education of a Silicon Valley Entrepreneur. In this book Komisar warns against the deferred life plan (if I only do this now, I can do that other thing later), and unfalteringly recommends what to some might describe as work-life balance. What he's really describing is pursuing your career and your life, and making what you are passionate about your life's work. This has certainly been the key recipe for my motivation in the past.
This is a timely message for me as I've just stepped out of my job. It gives me insight and again provides voice to some of the thoughts I had as I made my decision to leave and at the same time gives me courage to be selective of my new role and only go for things that I'm passionate about.
