some key points to judge the person

We can judge person by the way they talk, by the body language they used, by the experience, dude. As experience increases, you can judge their psychology

I don't think I can be properly judged based on my handwriting because I have different handwriting styles and I use different styles whenever I feel like it. Sometimes my writing is slanting, sometimes all caps, sometimes thin sharp letters, sometimes rounded. So I guess the handwriting psychology of me can never be accurate.
