There are two books which I keep coming back to learn from:

* Structure and Interpretation of Computer Programs: SICP changed the way I view programming. It's an excellent intro to the mindset of solving problems with code and how to iteratively build up a software design. You need to be comfortable with Scheme, though, in order to get the most out of the book.

* The Mythical Man-Month: Not strictly about programming but more on how to succeed with software projects. Hence, The Mythical Man-Month is more about people than code, which is why it has aged so well: people is a fairly stable construct.
