When talking to a potential customer, I can usually tell in a minute or less if they are going to be problematic. Call it intuition. Call it sixth sense. Or simply chalk it up to over ten years of experience. It usually starts with a gut feeling that tells you, “Don’t take on this new client, it is going to be more trouble than its worth.” It is then up to you to decide whether to listen to that still small voice or go against it and sell out for the money. Everytime I have done the latter, I have lived to regret it. Fortunately the longer I do this, I learn from past mistakes and pay more attention to the voice inside my head.
