I really like the Mixergy mission:
The Mixergy Mission is to give you an alternative to the “know-it-all, professional gurus.” I want to convince you that no single person knows it all. I want to show you that the best way to grow is to learn from a mix of smart people who are willing to share their expertise and experiences.
The Mixergy Mission is to encourage YOU to have a mission, not just a startup, not just a company, but a calling.
The Mixergy Mission is to act as a counter-weight to all the venture capitalists who’ll try to convince you that the only reason to build a business today is so you can flip it tomorrow. The world isn’t changed by people who have an eye on the exit.
The Mixergy Mission is to convince you to follow a vision so big and important that you can’t do it alone. Then I want to give you a mix of wicked-smart people who will help you achieve it.
