I know most lawyers have been in this situation: Heading into the first meeting of the day, feeling ready to take on whatever challenges await, until that confident attitude falls victim to someone whose constant complaining and negativity turns the “can-do” mood into “why bother?”

Most people have experienced times when one person’s bad attitude sends us looking for an economy-size bottle of St. John’s Wort. Unfortunately, these days, negativity is all around us. Firm layoffs continue unabated, the newscast fits more calamity into the first five minutes than seems humanly possible, and even the briefest glance at the stock market turns my stomach into knots. Yet there has never been a more important time to resist pessimism. That simple act can do quite a lot.
