Listen to customers and you will hear them. Look carefully at customers and you will see them. Do both and you will understand them.
Procrastination is the beginning of poor performance.
Meeting expectations is good. Exceeding expectations is better.
Make your upper limit, no limit.
Be the exception to the rule. It's the surest way to become exceptional.
When customers' expectations change faster than your willingness or ability to serve them, you can be sure they'll be someone else's customers soon.
