In business, your ability to adapt and change is often what separates successful entrepreneurs from those who are stuck in obscurity.

Some are good at spotting trends, some are good to adapting to them, but a few highly successful entrepreneurs have learned how to become an agent of change, someone who embraces the idea of adaptability and even encourages it as a way to push his or her business forward.

When you become an agent of change, you realize that your own ability to adapt starts with changing your own attitude, the world around you, your employees, and your product.

Here are a few quotes on how to make it happen, taken from well-known change agents. Which quote inspires you the most? Let me know directly by e-mail or in comments.
