From Steve Jobs to Thomas Jefferson, these quotes will inspire you to become a better leader.

Being a leader is no easy task — it takes hard work, courage and risk-taking. Being able to find solutions, solve problems and make things better are vital components to effective leadership. Positioning yourself as a role model for people to follow means doing things that will better improve your employees, community or even the world.

Take it from some of the most successful business leaders of today. Steve Jobs not only built the Apple empire, but the products he created ultimately helped improve the world as a whole. It’s similar for Mark Zuckerberg and Facebook. While he started creating a simple social platform for Harvard students, Zuckerberg ultimately led the company to become a network connecting nearly 2 billion people around the world.
