This is only one of these "must-read book list", what you can do is search several of them and see which ones are quoted by almost everyone!

About "everything" I would rate the following books very highly, for their sheer usefulness:

- Thinking Fast and Slow (really do the exercises!)

- then Neuroleadership which describes the purpose of brain structures, it's somehow wider than kahneman

- A Mind for Numbers (include very useful data points for knowledge workers)

- Distinction: A Social Critique of the Judgement of Taste

- Cutting Through Spiritual Materialism

About programming I would rate the following books highly, but at the same time it seems a bit fruitless to me to read about programming, rather than spending more time reading about psychology or sociology:

- the Economics of Software Quality

- Peopleware

- Pragmatic programmer

- Mythical Man month

^you'll see that these books are hardly kept secret, it's just that people quote them but don't actually read them, or so it seems.
