A clear and complete signature shows a person who is open, straightforward, and willing to share who they are with others. An indecipherable signature, on the other hand, may reveal a person who is arrogant and self-important. Think, for a second, about what a signature really is—a statement, repeated and refined over decades, that serves as a one-of-a-kind representation of an individual. It binds you to legal documents. It authorizes your purchases. In other words, it’s yours—and that’s why signature analysis is so revealing.
