What are 5 must-read books for people in their 20s?

In Never Eat Alone, Ferrazzi lays out the specific steps—and inner mindset—he uses to reach out to connect with the thousands of colleagues, friends, and associates on his contacts list, people he has helped and who have helped him. And in the time since Never Eat Alone was published in 2005, the rise of social media and new, collaborative management styles have only made Ferrazzi’s advice more essential for anyone hoping to get ahead in business.

He then distils his system of reaching out to people into practical, proven principles. Among them:

Don’t keep score: It’s never simply about getting what you want. It’s about getting what you want and making sure that the people who are important to you get what they want, too.
“Ping” constantly: The ins and outs of reaching out to those in your circle of contacts all the time—not just when you need something.
Never Eat Alone: The dynamics of status are the same whether you’re working at a corporation or attending a social event—“invisibility” is a fate worse than failure. 
Become the “King of Content”: How to use social media sites like LinkedIn, Twitter, and Facebook to make meaningful connections, spark engagement, and curate a network of people who can help you with your interests and goals. 

Linchpin: Are You Indispensable? by Seth Godin

This life-changing manifesto shows how you have the potential to make a huge difference wherever you are. 

Few authors have had the kind of lasting impact and global reach that Seth Godin has had. 
 In Linchpin, he turns his attention to the individual and explains how anyone can make a significant impact within their organization.

There used to be two teams in every workplace: management and labour. Now there’s a third team, the linchpins. These people figure out what to do when there’s no rule book. They delight and challenge their customers and peers. They love their work, pour their best selves into it, and turn each day into a kind of art. 
In today’s working world, we need to consistently find ways to add value and stand out from the crowd by making ourselves indispensable. This brilliant and thought-provoking piece of work will inspire you to overcome your “lazy brain” and create your own path to success.

Art of War by Sun Tzu

Written in the 6th century B.C., The Art of War remains the ultimate guide to combat strategy. Sun Tzu explains when and how to engage opponents in order to prevail in difficult situations. Instead of describing the logistics of warfare, he shows the reader how to succeed by motivating soldiers and leveraging tactical advantages. In short, he explains how to win the battle of wits. Though it was written for the battlefield, The Art of War contains valuable advice for other endeavors as well. Tzu’s work has been lauded by sports coaches, business executives, and other leaders of the 21st century. 

As a study of the anatomy of organizations in conflict, The Art of War applies to competition and conflict in general, on every level from the interpersonal to the international. Its aim is invincibility, victory without battle, and unassailable strength through understanding of the physics, politics, and psychology of conflict.

Arthashastra by Kautilya

What Max Weber said about this book truly makes it great:

“Truly radical “Machiavellianism”, in the popular sense of that word, is classically expressed in Indian literature in the Arthashastra of Kautilya (written long before the birth of Christ, ostensibly in the time of Chandragupta): compared to it, Machiavelli’s The Prince is harmless“

An extraordinarily detailed manual on statecraft and the science of living by one of classical India’s greatest minds; Kautilya; also known as Chanakya and Vishnugupta; wrote the Arthashastra not later than 150 AD though the date has not been conclusively established. Legend has it that he was either a Brahmin from Kerala or from north India; however; it is certain that Kautilya was the man who destroyed the Nanda dynasty and installed Chandragupta Maurya as the King of Magadha. A master strategist who was well-versed in the Vedas and adept at creating intrigues and devising political stratagems; Kautilya’s genius is reflected in his Arthashastra which is the most comprehensive treatise of statecraft of classical times. 

The text contains fifteen books which cover numerous topics viz.; the King; a complete code of law; foreign policy; secret and occult practices and so on. The Arthashastra is written mainly in prose but also incorporates 380 shlokas. 

Artha; literally wealth; is one of four supreme aims prescribed by Hindu tradition. However; it has a much wider significance and the material well-being of individuals is just a part of it. In accordance with this; Kautilya’s Arthashastra maintains that the state or government of a country has a vital role to play in maintaining the material status of both the nation and its people. Therefore; a significant part of the Arthashastra has to do with the science of economics. When it deals with the science of politics; the Arthashastra describes in detail the art of government in its widest sense—the maintenance of law and order as also of an efficient administrative machinery.
