- Influence by Cialdini

CLR Algorithms book

Skiena's Algorithm Design Manual

"A Guide to the Good Life" by William Irvine. It's an approachable guide to stoicism and it helped me become less attached and less anxious about things that I have no control over. I really value the increased peace of mind.

Switch by the Heath brothers is excellent

the one that I loved most was "Give and Take" by Adam Grant.

Reality Check by Guy Kawasaki is excellent, and covers everything from PR to marketing to legal.

I have heard good things about this book but have not read it yet.

I really liked Succeed by Halvorson

- Think Twice by Mauboussin

Thinkertoys, is also very good

Both book are a great blend of interesting studies and practical advice.
