Just a gentle reminder that, contrary to the old cliché, time is more valuable than money.
I called a client of mine in Florida and got his voicemail. He had a very professional, pleasant greeting, and - right out of our Playbook - at the end of the voicemail he said “I return messages between 3 and 4 pm every day. If your matter is urgent, please contact so and so”. He is projecting to his clients and anybody else that he values his time. He guards his time, and unless and until you do, nobody else will.
