Because these are the signs that reveal the unique or creative personality. There are no rules here. Every unique or creative personality breaks the mould.

Individuality, uniqueness, imagination and the ever-present ability to change is what it's all about. Your handwriting resonates with the unique quality of life that radiates through your personality. It reflects the emotions, thoughts and attitudes of your unique and special personality. Every person is special in some way and is different from every other person on earth. Even the personalities of identical twins are different because they are affected by influences that impact on their lives in different ways.
