One of the nasty circumstances is that you can lose clients and frankly, others will be glad. What you lose, they gain. One can never expect that good service, wise counsel and great work will reward. Sometimes it doesn't. Clients run out of money.
Clients retire and new contacts come in.
The good part of this gloomy outlook is that it keeps the practitioner alert. One's feelers are always in the air like an ant's antennae, sensing what is happening, second-guessing and watching. Sure, there are clients that are old shoe in their comfort and familiarity, but they are the ones that you should guard most closely. It is tempting to take them for granted, to treat them like a friend rather than a client to be served with attentiveness. Service is an act of will.
