Things I partially read and hope to complete some time:
1. The music of Primes
2. Traction
3. Founders at work
4. Your Memory: How it works and how to improve it
Things I would recommend: Fermat's Enigma and The Code Book are very interesting reads if you are into Mathematics. They are both written very well and you don't need to know too much of Mathematics to understand it. On the other hand The Music of Primes started of very interesting and then got a bit too heavy for an evening read. If you can chug along I think it would be a good one too.
Of all the self help books I mentioned I think Duhiggs Smarter, faster better is the one that stands out. It is more of an analysis of various teams and people and how they got to work efficiently.
Founders at work is a long read but something that you can read a chapter independently and that's why it is under half read but definitely something to look at.
