Fear. How many of our decisions are driven by this unpleasant emotion that often controls our lives? Afraid of seeing the doctor about a persistent cough, fearing a terminal diagnosis. Afraid of telling our adult children what we actually want, because it may hurt their feelings. Afraid of starting a new activity because we might look silly or inept. Afraid of making an emotional commitment because it might not be shared — or last. And afraid of the unknown when an overzealous imagination conjures up only the worst that could happen.
