Great post by Seth Godin:

Yes, we frequently sell ourselves too short. We don't ask for compensation commensurate with the value we create. It's a form of hiding. But the most common form of this hiding is not merely lowering the price. No, the mistake we make is in not telling stories that create more value, in not doing the hard work of building something unique and worth seeking out.

Create stuff that people value and that is in scarce supply. Focus on leaving the world a better place than you found it.
