People write things out by hand less and less. However, the specific way an individual writes words and letters can say a lot about him or her.
Graphology is the study of script, and it explains so much about a person's likes and dislikes. There's even some proof that serial killers can be identified by their handwriting. Many people would be surprised to learn that their sloppy signatures indicate a lot more than just laziness. Handwriting can explain personalities, too.
You can cross your T's at either the top of the letter or in the middle. If you cross at the top, you're probably ambitious and optimistic. A middle cross could mean that you're confident and comfortable in your own skin. If your T's have a long cross, you might be determined and a little stubborn. Experts think lazy people tend to prefer shorter crosses.
People that use large letters are likely to be very jovial and outgoing. Handwriting expert Sheila Lowe says that a bride or groom's mood can be determined by looking at their handwritten wedding invitations. If the hosts are excited, the letters will probably be "on the larger side - larger than medium which is 3 mm high."
Some people use their handwriting to channel how they feel. Introverts, for example, may use smaller than average script because they don't want to draw undue attention to themselves or their writing. Graphologist Sheila Lowe also suggests unhappy people might prefer smaller letters. She notes, "If you’re feeling sad or contemplative, then the writing tends to get smaller — it’s like you want to disappear."
Doctors tend to have sloppy signatures because they rush a lot. But extremely private people might also have illegible signatures, perhaps, because they subconsciously don't want anyone knowing how to spell their respective names. Alternatively, a confident, outgoing person might have a clear, legible signature. These extroverts may want everyone to recognize their work.
