My background is mainly in BD (tech) and policy (US & international gov) and I've always found business books with the exception of How to Win Friends and Influence People to be incredibly lacking. Instead, some of the most influential books for me have been sci-fi or more in the future prediction category.
1) Stand on Zanzibar: Helped me understand one direction of a potential world unfolding and stands out as incredibly prescient
2) Sovereign Individual: Helped me understand emerging tech trends potential impact on how government/society is organized
3) The Unbearable Lightness of Being: Helped me better understand relationships, human needs, and dealing with impossible choices
