Handwriting analysts can tell a lot about your personality from a simple signature. They look at everything, including the slope of your letters, their legibility, the space between them, how hard the pen is pressed into the paper and so much more.
Because your signature is your most personal example of your own handwriting, there's a lot of information jam-packed into it. This signature from Mark Zuckerberg, a man who has become a billionaire off the acquisition of the private information of others, indicates to experts that he is actually a very private man. People who only sign their names with initials tend not to share much about themselves publicly.
This signature of Bradley Cooper says that he is a man who oozes confidence, is direct and blunt, and may be both private and uncomplicated. The fact that it is illegible also indicates that he has a sharp intelligence and a busy lifestyle. All these traits are exactly how we pictured Bradley in all of our dreams.
Scarlett Johansson, like most of us, has a complicated personality (at least that's what her handwriting indicates). If you tend to sign your name differently depending on the document, you likely have different sides of your personality that you portray in different situations. The downward leaning slant of her letters shows she's more cautious and maybe even slightly pessimistic.
Take some time to learn about your signature, your handwriting, and all the fun little details it portrays about you to the outside world. Remember that it ”” like your personality ”” can be tweaked over time with practice.
