Instead of just asking 'How did I do?' ask 'How can I do more?'
Service is the ultimate edge. Keep it sharp.
Could you achieve the possible without trying? Could you achieve the impossible if you refuse to stop trying?
Say it with words. Show it with action.
The right measure is not how many customers you've got, but how closely you hold them.
The bottom line is a by-product of taking care of your main product - your customers.
