We usually attend to needs first and it is not always wrong. However, we must know when is enough and to stop.
The problem is, we get so engrossed chasing a need that it produces behavior that become hard wired (habits) into our neurology. These hard-to-break habits lead to neglect or worse, conflict with our values.
Soon, the values that are sitting in our unconscious will start gnawing at our conscience, producing the all-too-familiar emotions of guilt, anger, fear, regret and/or sadness. These adversely affect work performance, productivity and relationships, not to mention health.
