Have you earned the right to lead? Ten of the biggest mistakes leaders make

There are people in every organization whose titles indicate they are leaders. Often, and unfortunately, their employees beg to differ. Oh, they don’t say it directly, not to the boss’s face, anyway. They say it with their ho-hum performance, their games of avoidance, their dearth of enthusiasm. Leaders—real leaders who have mastered their craft—don’t preside over such lackluster followers. If reading this makes you squirm with recognition, leadership expert John Hamm says you may have a problem lurking.

“When times are good, not-so-great leaders can get by,” says Hamm, author of Unusually Excellent: The Necessary Nine Skills Required for the Practice of Great Leadership. “They’re cushioned by a surplus of cash, and their missteps are covered up by the thrill of top-line growth, which hides a multitude of sins. But when the cloak of prosperity falls away, their mediocrity is ruthlessly exposed.

Hamm has spent his career studying the practitioners of great leadership via his work as a venture capitalist, board member, high-level consultant, and professor of leadership at the Leavey School of Business at Santa Clara University. In his new book, he shares what he has learned and brings those lessons to life with real-world stories.

“These aren’t radically new ideas,” asserts Hamm. “Human nature hasn’t changed that much over the millennia, so neither have the core laws of leadership. It’s just that in the heat of the day-to-day battle, leaders inevitably lose their grip on the basic principles of leadership. In other cases, they never learned these fundamentals or mastered them earlier in their career. And finally, sad to say, some people just aren’t cut out to lead and need to understand why.”

Think about it this way, he says. Anyone can snap a photo that looks okay or cook a meal that satiates hunger. However, when an award-winning photographer takes the picture, or a five-star chef prepares dinner, anyone can tell a master has been at work. The same is true of leadership. The small deficiencies in how the novice leads, as opposed to the unusually excellent professional, create a radical difference in the outcome.

So how can you tell whether you really are a great leader in the minds of your employees—or whether, to paraphrase the old television commercial, you’re just playing one on TV? Unfortunately, the depth and breadth of the mistakes you make often tell the true tale.

Below, excerpted from Unusually Excellent, Hamm reveals ten of the most common, deeply destructive mistakes organizational leaders make.
