Read Godel Escher Bach from Douglas Hofstadter, easy to get into with plenty of interesting observations in a series of short stories.
https://en.wikipedia.org/wiki/G%C3%B6del,_Escher,_Bach
By exploring common themes in the lives and works of logician Kurt Gödel, artist M. C. Escher and composer Johann Sebastian Bach, GEB expounds concepts fundamental to mathematics, symmetry, and intelligence. Through illustration and analysis, the book discusses how self-reference and formal rules allow systems to acquire meaning despite being made of "meaningless" elements. It also discusses what it means to communicate, how knowledge can be represented and stored, the methods and limitations of symbolic representation, and even the fundamental notion of "meaning" itself.
In response to confusion over the book's theme, Hofstadter has emphasized that GEB is not about mathematics, art, and music but rather about how cognition and thinking emerge from well-hidden neurological mechanisms. In the book, he presents an analogy about how the individual neurons of the brain coordinate to create a unified sense of a coherent mind by comparing it to the social organization displayed in a colony of ants
Or go for something lighter from another Douglas (Adams) and start with the Hitchhiker's guide to the galaxy or Dirk Gentlys holistic detective agency. Timeless classics.
