15 Books Guaranteed to Make You More Intelligent

Books to make you more intelligent

1. Thinking, Fast and Slow by Daniel Kahneman

Source: Amazon

So much of today’s success comes from having the right mindset for business. This book is dedicated to showing you how to think methodically and rapidly as well as how to know when to make faster or slower decisions. You want to be quick on your feet but don’t want to rush into a decision that needs more contemplation. 

In Thinking, Fast and Slow (Farrar, Straus and Giroux, 2011), author Daniel Kahneman teaches both a “fast system” and a “slow system” to help you determine when and how to use each thinking speed. When you’re brainstorming new marketing ideas, for example, you may want to implement fast thinking to churn out organic ideas. To refine and execute those ideas, though, you may shift into slow thinking. Mastering both styles can be immensely helpful for entrepreneurs and professionals.

In A Short History of Nearly Everything (Broadway Books, 2003), Bill Bryson shares information across many areas of science related to the universe and how we got to where we are in human history. Along the way, Bryson adds some heavy information on physics, biology, chemistry and more. 

When you can discuss how and why we might be here as well as our purpose, you could impress more than a few people in conversation. More than that, though, it can help you understand your business’s place in society. What’s your value proposition? Who do you serve? What fundamental human problems does your business solve? Getting existential about humanity can help you get existential about your business, too.

His direct language and historical examples from Chinese military engagements of his day are timeless.

14. Meditations by Marcus Aurelius

Source: Amazon

Marcus Aurelius was a Roman emperor, but he also had some pretty down-to-earth insights modern leaders and entrepreneurs may find useful. Historians believe Aurelius’ Meditations weren’t intended for public consumption but were instead a series of private notes to himself as he navigated his life and shaped his personal philosophy. For business leaders, Aurelius’s book offers a reminder to focus on the big picture and avoid getting bogged down in minor frustrations. It also extols leaders who maintain virtues like courage, compassion, and curiosity. 

While much of Meditations may seem existential, its wisdom can easily be applied to managing a business and leading a team without losing one’s sense of self. Aurelius was the leader of one of the greatest empires human civilization has ever seen. So, naturally, he has a thing or two to say about the characteristics every great leader should cultivate and the challenges they’ll have to overcome.

15. Man and His Symbols by Carl G. Jung, et. al.

Source: Amazon

You may think to yourself, “What do symbols have to do with business?” One look at all the most iconic brands and the feelings they evoke within their customers can answer that question. 

In Man and His Symbols (Dell, 1968), one of the last written works psychiatrist Carl Jung contributed to, Jungian psychologists describe the importance of symbols in human life. The book describes how symbols appear in dreams, religion, art and elsewhere, digging deep into their importance and what individuals can learn from their collective imagery. 

For businesses, symbolism is a key means of communicating with customers. This goes beyond brand logos and into the way businesses and their leaders carry themselves, not just in what they say but in what they do. Symbols run deep in human consciousness, which gives them great power. Businesses that can tap into an understanding of how symbols compel humans in myriad ways can better build a relationship with customers. 

Whether these books change how you think, decide or act, others will begin to notice incremental improvements in your intelligence. This could mean greater respect at work, a jump in the influence you have over others or even a fast pass to a spot on Jeopardy.

How reading helps you in business

If you aren’t already sold on the idea of reading more books, here are five ways it can help you in business and life.

Strengthens business skills

Many of the books on this list offer insights that can help improve leadership styles, strategic planning, daily habits and more. While it will still take putting these ideas into practice to see improvement in your skills, guidance and wisdom are all available in these books. Entrepreneurs are great at learning from other people and drawing inspiration from all sorts of places, and it’s no different when it comes to cracking a book. If you apply the lessons from the books in our list, you’ll undoubtedly begin to see tangible changes in the skills it takes to make your business successful.

Improves reading comprehension 

Reading exposes you to information you might have otherwise never learned. As reported by WordsRated, people who read regularly have a roughly 50 percent increase in their vocabulary and fact-based knowledge, compared to those who don’t read often. In addition to gaining more expertise from the books you read, you’ll improve your ability to comprehend information. This makes it easier to read between the lines, understand any hidden messages in communications you receive from others and see the bigger picture. 

Improves communication skills

Listening to others’ ideas and how they communicate them can help you learn how to communicate more effectively and ensure your ideas come across clearly. This can help with public speaking as you learn the flow of words and sentences, how conversations naturally occur and what structures there are for expressing certain ideas or topics. This is useful when networking or communicating with people within your business. Conversations will be more effective, and you will be seen as a great communicator with high emotional intelligence.

Reduces stress

Running a small business can get hectic and stressful. But remember, taking time off to relax is as necessary as working hard. A simple way to do this is by reading. Just six minutes of reading a day can reduce stress levels significantly, even more so than music or exercise. Plus, it has the added benefit of potentially lowering blood pressure and heart rate. So, not only does reading enhance your knowledge, but it also bolsters both your physical and mental health.

Helps you become a better writer 

Writing is essential in business. You use it for memos, emails, social media posts and official documents. When you read, you expose yourself to a variety of voices and styles, which can help you learn different ways of communicating ideas. You’ll learn different tactics, such as using facts to support your points or grabbing attention with various writing styles. Plus, the more you read, the more you will have a beefed-up vocabulary.
