"Summa Technologiae" by Stanislaw Lem. It's the book about everything existing, possible and impossible too. For me it gives motivation to learn new, think about something new, try to find limits of what I already know.

"Mathematician's Apology" by G.H.Hardy. IDK why exactly this book (essay?) influenced me. I'm not a mathematician but I certainly found something that touches me.

"ANSI Common Lisp" by Paul Graham. I did not became a lisper because of that but it helped me to came out of my cave. I considered myself an experienced programmer but that was something about "other" programming. I remember the feeling that I had a secret magical weapon in my hands.

"Programming Erlang" by Joe Armstrong. This book is not about Erlang mainly but about ideas and conceptions behind Erlang. Actor model, messaging, "let it fail", "happy path" - all that influenced me a lot.

"Data Warehouse Toolkit: The Definitive Guide to Dimensional Modelling" by Ralph Kimball and Margy Ross. The book about how to make data clean, inambigious and easy to understand.
