On Yom Kippur, there are a total of ten Viduys, or confessions, through the course of the day. The goal is to break the monotony of repeating the same thing over and over again.
There are many attempts to make our confession more relevant, by the various commentators of the Machzor. For example, in the category of stealing, they might include stealing one's sleep. Or, pretending to buy something in a store and misleading the shopkeeper. Violating a confidence is an example of misusing speech.
The Rambam would suggest that we focus on correcting negative personality traits that we might have. These could be things like anger, pride, and jealousy. Whatever the case may be, we should try to make our וידוי meaningful and with content.
