I'm a longtime handwriting analysis practitioner who has been doing this for the pure fun of it. I started doing handwriting analysis when I was a reporter and my colleague, who worked on the police beat, kept getting letters from people in prison. All of them were innocent, of course.
There was some crazy handwriting in that bunch of letters, and a financial columnist who was schooled in handwriting study, showed me a few things to get started on my own. The 'felon's claw,' the meaning of uneven pressure, and the obsessive letter spacing of a psychotic I've been studying ever since.
I also work as a content creator and online marketer when I'm not analyzing handwriting. You'll find me at http://earnplaygrow.com/start (get some great freebies there) and at http://cashsystemsecret.com where I'll share some of my secrets to living well and working at home.
