What is the difference between a mission statement and a vision statement?

This seems to be a question that torments organizations of all kinds and size.

What is the difference between a mission statement and a vision statement?

Here’s how we explain it to clients:

Your mission is what you do best every single day, and your vision is what the future will be like because you deliver on that mission so brilliantly every day.

Each one should be no more than 10 words apiece.  No long paragraphs, no lengthy missives.  Not 3 things or 5 things.

10 words for each.

Can you do it?
