Essentialism: The Disciplined Pursuit of Less is a self-help book written by Greg McKeown. The core message of this book is the outline of a minimalist approach to every kind of task or obligation. Rather than focusing on multitasking and on doing "more things at once," the author suggests that we should instead be focusing on doing what is important. Since we live in a world where speed is everything and where the most important thing is to know how to successfully combine speed and efficiency, people are often told that multitasking is what it is all about. If we read this book, we will see that there are easier ways to get things done.
