I contend with the clients we work with we have our IDEAL clients, then the 90% we can work with, then the OIL and WATER clients. The latter do not mix with us.
Remember That All Important Chemistry With Your Clients.
Some people you cannot work with smoothly. They demand too much, they don't like how you communicate with them, you are irritated when their phone calls or emails or text arrives. Cut them loose. Save everyone the hassle. YOU two for some reason are a mismatch. Pass them off to your favorite enemy LOL. Seriously, work to move them on, just not be part of YOUR LIFE.
