Never Split the Difference - I loved this book and would highly recommend it to sharpen your negotiation skills.
Extreme Ownership - I also really enjoyed this book. I listened to the audio and it was read by the authors. Both Navy Seals, the stories they used about their time in war was very eye opening. The concepts are all about leadership, and if you a manager or part of a team, you will get some benefit.
Getting Things Done - 2001 edition, very practical approach to organizing everything on your plate. I will probably re-read this again.
Learning How to Learn: How to Succeed in School Without Spending All Your Time Studying; A Guide for Kids and Teens - a great book that has great tips on learning for kids and adults.
A Philosophy of Software Design - still reading it, I really am enjoying it so far. I like the big picture approach it takes to discussing software design and complexity.
Mindset - I just started this book. So far it is just explaining the general concept in different ways. I am hoping the latter part will get into some practical tips and methods.
