Anthony Iannarino never set out to become a salesman. He fell into his profession by accident, and now has turned his focus to a question that's been debated for at least a century: Why are a small number of salespeople in any field hugely successful, while the rest are stuck with mediocre results at best? Since then, and for over 25 years, he has read hundreds of books, tested countless strategies, and interviewed dozens of the best salespeople to figure out what sets the extraordinary ones apart from the rest.

For decades we've been told that positive thinking is the key to a happy, rich life. "F*ck positivity," Mark Manson says. "Let's be honest, shit is f*cked, and we have to live with it." In his wildly popular Internet blog, Manson doesn't sugarcoat or equivocate. He tells it like it is - a dose of raw, refreshing, honest truth that is sorely lacking today. The Subtle Art of Not Giving a F*ck is his antidote to the coddling, let's-all-feel-good mind-set that has infected modern society and spoiled a generation, rewarding them with gold medals just for showing up.

We're in the middle of an epidemic of average. So-called "normal" people get up every day, go to work, do what's asked of them, leave promptly at five, and return home to sit on the couch and watch TV. Society tells us that this is what it means to lead a balanced life. Don't stress too much or work too hard. Your career isn't everything. But Grant Cardone thinks this preoccupation with balance has really just given an excuse to be mediocre.
