It can be lonely at the top, and being in a leadership position will remind you very quickly of that old adage. By nature of the role, leaders are often all on their own. Whether it’s a high-stress job as CEO of an international firm, or a smaller position as the manager of a small local business, a leader is saddled with accountability and responsibility that must be managed alone.

We often reach within ourselves to find strength or inspiration, but there are times when that inner solace can fall short. That’s when we can find value in looking outside of ourselves, to other leaders and inspirational figures across culture and throughout history.

Whether you’re a business owner, teacher, chairperson, entrepreneur, or just looking to inspire those you lead, here are thirty powerful quotes to keep in mind:

4. “I’ve missed more than 9000 shots in my career. I’ve lost almost 300 games. Twenty-six times I’ve been trusted to take the game winning shot and missed. I’ve failed over and over and over again in my life. And that is why I succeed.” — Michael Jordan

5. “Twenty years from now you will be more disappointed by the things that you didn’t do than by the ones you did do, so throw off the bowlines, sail away from safe harbor, catch the trade winds in your sails. Explore. Dream. Discover.” — Mark Twain

12. “A leader is like a shepherd. He stays behind the flock, letting the most nimble go out ahead, whereupon the others follow, not realizing that all along they are being directed from behind.”  —  Nelson Mandela

15. “The day the soldiers stop bringing you their problems is the day you stopped leading them. They have either lost confidence that you can help them or concluded that you do not care. Either case is a failure of leadership.” — Colin Powell

16. “There is a difference between being a leader and being a boss. Both are based on authority. A boss demands blind obedience; a leader earns his authority through understanding and trust.” — Klaus Balkenhol

17. “A leader isn’t someone who forces others to make him stronger; a leader is someone willing to give his strength to others so that they may have the strength to stand on their own.” — Beth Revis

18. “Control is not leadership; management is not leadership; leadership is leadership. If you seek to lead, invest at least 50 percent of your time in leading yourself–your own purpose, ethics, principles, motivation, conduct.

19. “Effective leadership is not about making speeches or being liked; leadership is defined by results, not attributes.” — Peter F. Drucker
