Far better to be an uncharismatic leader who gets the right people to confront the brutal facts than to be a magnetic force of personality who leads compliant followers to disaster. If you have charisma, you can still build an enduring great company. But never forget: If your company cannot be great without your personal charisma to inspire, then it is not yet a great company.

I’d like to close this chapter with an essential caveat about persistence from Built to Last. Of all the paragraphs I’ve authored or co-authored in thirty years, this is one of the most essential for entrepreneurs and leaders of early-stage ventures, reproduced here as a reminder to keep firmly in mind as you build your company:

The builders of visionary companies were highly persistent, living to the motto: Never, never, never give up. But what to persist with? The company. Be prepared to kill, revise, or evolve an idea . . . but never give up on the company. If you equate the success of your company with the success of a specific idea—as many businesspeople do—then you’re more likely to give up on the company if that idea fails; and if that idea happens to succeed, you’re more likely to have an emotional love affair with that idea and stick with it too long, when the company should be moving vigorously on to other things. But if you see the ultimate creation as the company, not the execution of a specific idea . . . then you can persist beyond any specific idea—good or bad— and move toward becoming an enduring great institution.

Practice Productive Paranoia (Avoid the 5 Stages of Decline)

The first step in being built to last is don’t die. The only mistakes you can learn from are the ones you survive. Every company is vulnerable to decline. There’s no law of nature that the most successful companies will inevitably remain at the top. Any can fall and most eventually do. Entrepreneurs who build great companies differ from less successful comparisons in how they maintain hypervigilance in good times and bad. Leaders who navigate turbulence and stave off decline assume that conditions can unexpectedly change, violently and fast. They obsessively ask, “What if? What if? What if?” By preparing ahead of time, building reserves, preserving a margin of safety, bounding risk, and honing their discipline in good times and bad, they handle disruptions from a position of strength and flexibility. Productive paranoia helps inoculate organizations from falling into the 5 Stages of Decline that can stop the flywheel and destroy an organization. Those stages are (1) Hubris Born of Success, (2) Undisciplined Pursuit of More, (3) Denial of Risk and Peril, (4) Grasping for Salvation, and (5) Capitulation to Irrelevance or Death.

Your greatest challenge as a leader, then, is to honor each person’s legitimate fear of the unknown and, at the same time, to turn that fear into spiritedness. We, your followers, like the comfort of where we stand, yet know that the flow of events is pulling us inexorably into the unknown. So when we find something, anything, however slight, that lessens our uncertainty, we cling on for dear life.

As I near the end of all of that and think back on what I’ve learned, these are the ten principles that strike me as necessary to true leadership. I hope they’ll serve you as well as they’ve served me.

Optimism. One of the most important qualities of a good leader is optimism, a pragmatic enthusiasm for what can be achieved. Even in the face of difficult choices and less than ideal outcomes, an optimistic leader does not yield to pessimism. Simply put, people are not motivated or energized by pessimists.

Courage. The foundation of risk-taking is courage, and in everchanging, disrupted businesses, risk-taking is essential, innovation is vital, and true innovation occurs only when people have courage. This is true of acquisitions, investments, and capital allocations, and it particularly applies to creative decisions. Fear of failure destroys creativity.

Focus. Allocating time, energy, and resources to the strategies, problems, and projects that are of highest importance and value is extremely important, and it’s imperative to communicate your priorities clearly and often.

Decisiveness. All decisions, no matter how difficult, can and should be made in a timely way. Leaders must encourage a diversity of opinion balanced with the need to make and implement decisions. Chronic indecision is not only inefficient and counterproductive, but it is deeply corrosive to morale.

Curiosity. A deep and abiding curiosity enables the discovery of new people, places, and ideas, as well as an awareness and an understanding of the marketplace and its changing dynamics. The path to innovation begins with curiosity.

Fairness. Strong leadership embodies the fair and decent treatment of people. Empathy is essential, as is accessibility. People committing honest mistakes deserve second chances, and judging people too harshly generates fear and anxiety, which discourage communication and innovation. Nothing is worse to an organization than a culture of fear.

Thoughtfulness. Thoughtfulness is one of the most underrated elements of good leadership. It is the process of gaining knowledge, so an opinion rendered or decision made is more credible and more likely to be correct. It’s simply about taking the time to develop informed opinions.

Authenticity. Be genuine. Be honest. Don’t fake anything. Truth and authenticity breed respect and trust.

The Relentless Pursuit of Perfection. This doesn’t mean perfectionism at all costs, but it does mean a refusal to accept mediocrity or make excuses for something being “good enough.” If you believe that something can be made better, put in the effort to do it. If you’re in the business of making things, be in the business of making things great.

Integrity. Nothing is more important than the quality and integrity of an organization’s people and its product. A company’s success depends on setting high ethical standards for all things, big and small. Another way of saying this is: The way you do anything is the way you do everything.
