Enthusiastic service providers create enthusiastic customers.
No one ever delighted a customer by being 'good enough'.
Focus not on who you are, but on what you can do for others.
Promise too much and you'll have plenty of room to fail. Promise little and you'll have plenty of room to excel.
If you want to be the best, find the best in others.
Passion isn't always available. The committed get things done even without it.
