Always aim for 100 percent and you'll always know where to improve.
The right measure is not how many customers you've got, but how closely you hold them.
Enthusiastic service providers create enthusiastic customers.
Promise too much and you'll have plenty of room to fail. Promise little and you'll have plenty of room to excel.
Let your customers say, 'Well, here I am,' while you say, 'There you are!'.
Be confident enough to encourage confidence in others.
