I love the whooshing sound they make as they rush by....
II was talking with an artist friend who is busier than I am...I asked her if she ever felt overwhelmed and scattered as she works at her job as an artist... She told me she used to feel that way often, but she has learned to concentrates on one thing at a time. I tried it and of course it works.
It settles me down and focuses me on the job at hand...eases anxiety.
Another affirmation for staying in the moment.
