What my signature says about me

There is a version that signature is the part of our handwriting that says the most about our personality. But honestly I don’t beleve it.
Whene I was ten years old my signeture was the first lettes of my surname. Then I started to deslike it and now my signeture is just my name. According to the text first name represents private self, this implies that I have positive feelings about my childhood and that my ‘private’ self is more important to me than ‘public’ self. My signeture is descending, this means that I have a tendency to get depressed and give up when faced with problems, and lack self-confidence.
