One thing that I learned from the past 8 years of running my jewelry business is that the saying "Comparison is the thief of joy" is very true. 

But you know what else is true? The world is chock full of inspiration. It doesn't help you to compare and compete, but seeing what's out there can also encourage you to shoot for bigger and better. Sometimes when you are feeling stuck, take a look at what people in your industry are doing, and let yourself ride the waves on other people's enthusiasm. It's contagious!
