The first step to being amazing is to realize that you aren't. There are hundreds or thousands of coaches, and self help types who will tell you otherwise and some of them make a pretty good living at it. But they're wrong. It's not about you at all in fact. Your self confidence, your "personal brand", your (insert star quality here...). That's not how to become amazing. You become amazing when you lose sight of yourself and immerse every talent, skill, and ability into helping somebody else be amazing at something.
In short, you yourself are not the product you think you are—but what you teach or the tools you build or the services you provide become the bridge between you and the people you invest in. That bridge of course has two way traffic lanes and each destination on other side benefits from it.
Truly amazing people, products, brands and companies have a way of making others the star even more so than themselves. The bridge between the two is usually built on incredible value. And this is always where the focus needs to go—on building that bridge on foundation points which provide indisputable value to others. Do this, and you'll be amazing.
