I'm continueing my series of what to read during the quite christmas time. Hopefully you don't check the prices of cryptocurrencies every few hours [like me ;) ] and have some time to read good business books.

Short of ideas on what to read? Here they come:

'Lean In' by Sheryl Sandberg

Regardless of whether you agree with Sandberg's controversial theories, "Lean In" is a must-read for anyone looking to join the conversation around women and leadership.

In the book, she combines compelling research with moving personal stories to examine how women unintentionally undermine their professional progress. Moreover, she offers guidance for women and men looking to promote women's career success.

'The Power of Habit' by Charles Duhigg

While a book about the science of habit change might sound like it'll put you to sleep, "The Power of Habit" is anything but.

In fact, it's one of the most useful and entertaining books for young professionals looking to set themselves up for a lifetime of health and happiness.

Duhigg, an investigative reporter for The New York Times, explains how the road to success — whether that means quitting smoking or procrastinating — is paved with tiny behavior tweaks you can implement today.

It's a work that will make readers of any gender question their assumptions about what it really takes to succeed — and be satisfied — at work.

'How to Win Friends & Influence People' by Dale Carnegie

This book has remained a bestselling book since the time of the Great Depression for its timeless wisdom.

Carnegie's book, a favorite of legendary investor Warren Buffett's, is more focused on the psychology behind daily interactions and how to use an understanding of how people work to emerge as a leader and influencer.

'The Power Broker' by Robert Caro

Not understanding how powerful people work makes you vulnerable to their will.

This is why "The Power Broker," Caro's immense biography of the New York urban planner Robert Moses, is so essential.

If you want to see Machiavellian principles in action, read this.

Carnegie's language and references can be charmingly dated, but the core lessons on how to overcome conflict and inspire people to open up to you are just as valuable today as they were decades ago.
