Ask HN: SICP is often recommended as mind opener, what did you learn from it?

We all know SICP is recommended by experienced developers all over the internet as a mystical book that turns your mind inside out and makes you a better programmer and computer scientist after you work through it. If you are someone from that gang, what did you learn from SICP that really caused this transformation? What did it do differently than other programming languages or CS books? Have you had similar experiences with other books (Lisp based or not)?
