Preparation is good, but customers need results.
Stay in one place too long and the tide can overwhelm you. Ride the tide, surf the waves, stay on top of the changes.
Only a well-oiled machine runs smoothly.
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.
To see like a customer, be like a customer.
Your promise means more than the words you use to give it.
