My exterior is always calm. In fact a woman I work with called me quirky. I asked her why and she said " you are always calm". It's my exterior. Inside not so much. Inside my mind is always racing. Working three different "Jobs", raising a child and staying married for 22 years will do that to you. Finding calm to quiet the mind and quiet the nerves is always a challenge. This is what I've found that works:
Playing the Guitar - If you play an instrument you are lucky. It's magical the way music can change the mood and physically making the music happen is extra special.
Singing along to music. I still love being in the car when one of those special songs comes on. Volume goes up!
It's a good life.....
