If you believe something hard and long enough, you can turn it into reality. This is definitely the case when it comes to leadership. Through the power of intention--and a clear vision of the future--not only can you inspire the members of your team to do everything they can to achieve the organization's goals, but you can physically drive your organization forward.

According to executive coach Jeff Wolf, author of the book Seven Disciplines of a Leader, "To be a leader who makes things happen, you need to develop and maintain a positive belief system." Here are the four basic beliefs of all great leaders.

1. Our company is the best

We are proud to work for the best company in our community and in our industry, and we will do what it takes to maintain our place. We constantly look for ways to improve our company and the products and services we offer. If we must work harder and smarter to stay ahead of the rest of the pack, that's exactly what we will do.

2. Our services, people, and training are the best

Second best is not good enough--we recruit and hire the very best people we can find, and then we provide them with the training they need to do their jobs independently and well. As a result, our people create and deliver the very best products and services.

3. We are the best

We really are the best provider of the products we sell, and the services we deliver. We work hard to continuously improve our offerings, and we compare ourselves against the competition regularly to learn ways to stay ahead and do even better. We refuse to become complacent--we know that we are replaceable.

4. Our customers or clients are better off using us and our company

Not only does our company provide great value to our customers, but we leave them better off than if they didn't use us at all. It therefore becomes a no-brainer to buy products and services from us, rather than from our competitors. To preserve this advantage, we must always find ways to improve what we do, and to do it for less money.
