When most people speak publicly about themselves, there are two things you can usually count on. First, people tend to have a lot to say about themselves. Second, they have generally good things to say. You never hear politicians, for example, herald their mistakes or any misconduct. Doctors hang their diplomas or licenses on the wall, not malpractice lawsuits they may have lost. Some public speakers are self-deprecating, but usually as an attempt at humor in a self-serving way of feigning humility. The truth is that few of us want to publicly expose our failings and weaknesses.
