1. Peter Norvig's Design of Computer Programs course on Udacity probably singlehandedly changed my perspective on thinking and modeling software solutions to problems.

2. Crafting Interpreters by Robert Nystrom is of similar quality. There are a lot of 'oh that's how that works' moments in this book.

3. Doyle Brunson's Super System 2 is of a similar nature, but for poker. It's outdated these days because the nature of the game has changed so much due to the internet and a shift in meta strategy, but it's really insightful in understanding the human aspects of the game. His perspective as a 'gambler' rather than poker player is also unique, because he talks a lot about prop bets and identifying when you have an edge in a bet.

4. Stephen King's "On Writing" is a masterpiece of a memoir of a man and his craft. My own writing improved significantly as a result of this book.
