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.
