When you order a doormat, they charge per word. This financial restriction makes you think long and hard about what you want to say. The other restriction is that space is limited. So your thinking needs to be distilled down into the fewest number of words possible. (The doormat is good because it makes Twitter feel like a novel) If you can get your thinking about your business so simple that it can appear on a doormat, my bet is that you will have plenty of customers walking on it.
When everything seems to be going against you, remember that the airplane takes off against the wind, not with it. Henry Ford
