On the programming side:

* Thinking Forth by Leo Brodie

* Lisp In Small Pieces by Christian Queinnec

* Compilers (the Dragon Book) by Aho, Sethi, and Ullman

* Smalltalk-80 (the Blue Book) by Goldberg and Robson

But on the non-technical side, the book that probably had the biggest impact on my career was "What Color Is Your Parachute" by Richard Bolles. It is what convinced me I could transfer my skills from video game dev into another field and how to come up with a plan to do so.
