Cheers to those with a glass half-empty

In business, optimism is good and pessimism bad. Optimists have a monopoly on success, on happiness and even on longevity. Pessimists, with their long faces and dark thoughts are pariahs, thought fit for nothing in the gung-ho corporate world except possibly careers in journalism (where bad news is good news). Otherwise, they have a choice between the couch, the closet or the comedy circuit.
