Never get emotional. Emotion prevents you from thinking clearly and objectively because the situations become personal. It also increases your stress levels making you vulnerable to rash decisions and retaliatory or defensive behavior. It totally throws you off center and you lose sight of the problems and focus on personalities. As McCann explained at work, â€œa friend today is a foe tomorrow.â€ It is sometimes just the nature of business. Those who can, as Aetna Chairman and CEO Ron Williams mandates, â€œfocus on the problem; not the person,â€ will find greater success at work. Sonny was the emotional character in The Godfather--and he was killed!
