Your mission should you choose to accept it
How a great communicator defines a big audacious goal:
We will "put a man on the moon and return him safely by the end of the decade."
- John F. Kennedy
How the typical business executive would define the same goal:
"Our mission is to become the international leader in the space industry through maximum team-centered innovation and strategically targeted aerospace initiatives."
Thanks to Made to Stick for creating this example.
Too many software ventures have mission statements that sound like the latter. Don't try to define your mission so it covers all the bases and supports every contingency. Instead focus on defining your mission in terms that are simple, concrete, and emotionally compelling.
