I'm a graphologist and a clinician; I tend to get to know a little bit about people by peering at their handwriting. Looking at Barbara Streisand's signature, we do find the theme of duality. Barbra's first name (representing the private self) is scripted in one style of writing whereas her last name (representing her professional self) is scripted in a completely different style of writing.

Note how she loyally reproduces the copybook script she learned in school and, in so doing, shows us that, first and foremost, she values fitting in. Such writers, amiable and good-natured, easily lapse into people-pleasing. And they often harbor secret self-negating habits designed to help them keep insecurities at bay.

What do we know about the psychology of an Olympic athlete? The signature of Mark Spitz is worth examining. We can learn something about what it takes to excel in sports; also, in life.

What does your handwriting reveal? A lot. It reveals unique facets of your personality, but more importantly, if you are of a certain age, its trace attests to the care and sustained efforts of those who taught you how to write.
