Summer is a time to kick back, relax, and read a book. (And maybe try to figure out how to work a few hours less during the week.) These entrepreneurs have already picked the books they want to read. Steal their idea? Sure.

1. "I have two books on my bedside table that I'm eager to open. The first, The Singapore Story, is about the last prime minister of Singapore, Lee Kuan Yew. I admire Lee Kuan Yew greatly and consider him among the greatest leaders of our time, having fashioned Singapore into the modern, prosperous society is has become in less than 50 years. I find it useful to study the leadership styles of others -- especially what works and why. The second book, The Moscow Puzzles, is a compilation of recreational puzzles and brain teasers, including riddles and math problems. The brain is like a muscle -- it gets stronger with practice. These intense brain exercises train the brain for heavy analysis and complex decision-making." - Jaspreet Singh, Founder and CEO, Druva

2. "Coming of Age in the Milky Way by Timothy Ferris is excellent for anyone interested in the cosmos we live in and what we are made of. As leaders and entrepreneurs, we get caught in assumptions and biases about the narrow worlds we operate in, and reading this book reminded me yet again of the importance of challenging conventional wisdom and remaining open-minded to different possibilities."  Chandran Sankaran, CEO and co-founder, Zyme

3. "The Hard Thing About Hard Things by Ben Horowitz is a great summer read. I've rarely found value in management advice books that are either overflowing with platitudes or seem to exist in some stasis where everything is running smoothly. Ben's book is refreshing because it doesn't make running a company sound like a business school case study. He is very real and brutally honest about his own missteps, which helped me immensely when I was founding my company. Combine that with 90s rap lyrics to begin each chapter and some funny anecdotes and you've got an awesome read!" - Adam Edwards, Founder and VP of Client Services,  Metric Theory

4. "I'd recommend the  Management collection by Peter Drucker and Scaling Up by Verne Harish. The two books balance each other well, as Drucker is a visionary while Harish is a pure realist. Reading Drucker's essays made me realize how we've been stuck in our definitions of 'work' and how we suffer from not reinventing management to fit what 'work' really looks like today. On the other hand, Scaling Up is an amazing guide to building the habits necessary for growing any business. I've seen many VC-funded tech companies neglect these sometimes boring, but always necessary, practices: financial planning, habitual planning and check-ins for strategy, and rules for everything in-between." - Vlad Lokshin, CEO and Co-Founder of DarwinApps and Turtle Technologies

5. "One of the books I'll be reading this summer is Work Rules! I'm fascinated by how companies organize and prioritize as they scale. During my time at Salesforce, we used a company-wide process for prioritization and communication called the V2MOM. Google famously uses an approach called OKR (Objectives, Key Results). Work Rules! is written by the SVP of People Operations at Google and looks like a fascinating insight into how Google has managed to grow massively, while maintaining its innovation and agility.  Another book I'll be reading is The Big Data Business. There are so many books written by industry analysts on big data, but few from practitioners. Russ Glass runs LinkedIn's marketing products team and provides a fascinating guide for how companies can navigate the opportunities in big data for large and small companies. Finally, there's  Ready Player One. As the future of artificial intelligence and virtual reality gets closer every day, this book has been recommended to me as a fictional future that may be reality soon. Described as 'Willy Wonka meets the Matrix', I'm looking forward to learning how I'll be living my life in a decade." - Tim Barker, CEO, DataSift

6. "I'll be reading  Call of the Wild by Jack London this summer. It's a great piece of historical fiction that literally puts you in the middle of the Klondike Gold Rush in 1896, told from the viewpoint of a dog. It's a great 'escape' read, and perfect to read travelling or at home in an armchair." - Anderson Pugash, Owner/Founder, The Dorian, Palm House, Audio and Bergerac (San Francisco restaurants and bars)

7. "I just bought Chris Anderson's book  TED Talks: The Official TED Guide to Public Speaking.  Whether I am coaching a team of fitness performance coaches, leading a staff meeting, or training one of my clients through adjustments in their nutrition, my goal is that my words will speak directly to my audience, connect with their lives and excite them into action. Anderson and the TED leadership team have mastered this gift like no other." - Billy Polson, C.S.C.S and Founder, DIAKADI

8. "This summer one of the books I have my eye on is Mindfulness: An Eight-Week Plan for Finding Peace in a Frantic World by Mark Williams and Danny Penman. You can read a million self-help books about leadership, being an entrepreneur, scaling your business, being a better boss...the list goes on. But, the real challenge for many successful people is finding real feel-it-in-your-bones happiness. When you can be mindful in what you're doing, success is a much more satisfying thing." - Alyssa Marty, Founder,  Shine Yoga

9. "At a time when there is an increasing focus on maximizing return from all investments in sales, it is essential to consider how you can add value to your existing customers.  I try not to overtly push one of my own books, Account Planning in Salesforce, but I do strongly recommended it for business leaders this summer in particular. The book highlights best practices for account planning and helps business leaders identify the best ways to target and sell into existing customers. Most people know it is more cost effective to sell into existing customers, but they may not realize they are six times more likely to win business from an existing customer than a new one.  Strategic leaders will learn how to maximize the value of the relationships they have already built. Oh, and by the way, it is the only account planning book that has a rock playlist, and you might discover some tunes that will help you find some extra rhythm this summer." -​ Donal Daly, Founder and CEO, Altify

10. "The 15 Commitments of Conscious Leadership by Jim Dethmer, Diana Chapman, and Kaley Klemp is a book I highly recommend to those wanting to learn the keys of being a conscious leader. This book has enabled me to find both success and joy in building teams, creating products and serving customers. More specifically, I learned the importance of authenticity, candor and living with a commitment to win-win. On the shelf to read this summer is a book by the name of, Bringing Home the Dharma by Jack Kornfield. I am especially excited to read how Jack teaches the methods for staying awake regardless of where you are." -​ Jim Barnett, CEO and Cofounder of  Glint
