As an entrepreneur, I know firsthand that it's not always easy to be thankful for what you have. After all, I have to make payroll, meet with prospects, fulfill my speaking obligations, and try to make time for my wife, daughter, and five pets. I run the risk of getting too wrapped up in what I don't yet have that I might not focus on what I do have.

With that in mind, I try to step back and look at my favorite quotes about gratitude to inspire me:
