When the customer makes contact, he does not want a quote. He wants a commitment.
If it's not impossible, you may as well try. If it is impossible, at least you'll find out why.

Enjoy your work so that others may enjoy the results.
The right measure is not how many customers you've got, but how closely you hold them.
Constant acts of goodness are worth far more than rare acts of greatness.
