Size of your handwriting
You like working at your own pace as you are a detail oriented individual who prefers in-depth knowledge of a subject. You find it irritating that people always try to rush you and don't spend enough time learning the details and nuances of the subject.
You like leading and instructing others while working. You don’t prefer much detailed work as you tend to see the bigger picture. As long as someone gets their work done, you don't care about the route they have taken to get there.
