Mari Messer, in her book Pencil Dancing, listed Diane Ulmer's 4 symptoms of hurry sickness.
1. Deterioration of the Personality. Interest becomes narrow ... thoughts become dull and uninteresting.
2. Racing Mind. Anxious thoughts and loss of ability to focus create stress ..
3. Inability to Recollect Pleasant Memories. The mind is riveted on the future or stews about the past.
4. Inability to Experience Inner Contentment. The person has literally given up on savoring life's satisfying experiences.
This certainly gives food for thought about the need to have a balance of both hurriedness and quietness.
