Note the angle inward from the corner of her eyebrows to her hairline. This physical indicator illustrates a short attention span...or low concentration.
This trait is an important reminder that it is not better to have a short attention span, nor is it best to be able to concentrate to a state of external oblivion.
Recognizing your particular trait is what is important. If you have low concentration you may have been diagnosed as ADHD, when in reality you simply have a short attention span.
If your particular trait is high concentration, realize that you have difficulty in shifting your attention quickly from one focus to another.
