E-Myth (Revisited) by Michael Gerber
Michael Gerber does an excellent job at dispelling the myths surrounding the starting of a new business and showing how common assumptions become roadblocks for those who have already taken that step. Based on the premise that entrepreneurs make poor business people, E-Myth shines a guiding light on the life of how a successful business grows from infancy to maturity in a predictable and productive way.

Outliers by Malcolm Gladwell
In this book, Malcolm Gladwell dubs “outliers” as the best and brightest among us, the most famous and successful. Gladwell challenges the long-held notion of what makes a ‘self-made man’. Gladwell makes the assertion that superstars like Mozart and Bill Gates don’t arise out of nowhere and clarifies what makes these high achievers different. His belief is that we pay too much attention to what they are like and too little on where they are from – their culture, family, generation, and upbringing. Through case studies and bits of trivia, Outliers tears down the myth of individual merit to say that no one makes it alone and explores how culture, circumstance, timing, birth and luck account for success. It presents the case that the world would benefit if more people were granted opportunities to fulfill their remarkable potential.

Secrets of the Millionaire Mind by T. Harv Eker
Harv Eker believes that success is a learnable skill. Most notably, in Secrets of the Millionaire Mind, he suggests that from an early age we have a personal money and success blueprint etched into our subconscious mind that determines our financial well-being. Eker explains the principles of amassing wealth in two parts. Part I describes how our money blueprint works. Although initially it is shaped by childhood influences, it can be ‘revised’ continually to create and keep a high-level of financial success. Part II introduces the 17 ‘Wealth Files’ that give actionable steps to dramatically increase your income and accumulate wealth. Bottom line: if you think and act like financially successful people do, chances are good you’ll be wealthy too.

Start with Why by Simon Sinek
In 2009, when Simon Sinek started a movement, he began to show people that if they wanted to inspire and lead those around them, they needed to become more inspired themselves. Start with Why begins with a fundamental question: Why are some people and organizations more innovative, more influential, and more profitable than others? Sinek shows that some of the most persuasive and pioneering leaders in the world such as Steve Jobs and the Wright Brothers all started with their ‘WHY’. Their success hinged on the realization that people won’t buy into what they are touting until they understand the ‘WHY’ behind it. Start with Why illustrates this powerful idea through ‘The Golden Circle’ – a framework which successful organizations, movements and people think, act and communicate. This book can lead you to levels of success you never thought attainable.
