I learned this lesson a long time ago. My husband died and I was left with four children ranging in age from 6-16. The youngest was finishing her kindergarten year and a friend had invited me to walk the track at the high school. My mom was in town for the end of year festivities and offered to babysit. I was in a dress and changed my shoes in the car. I remember feeling "cool", like a NYC businesswoman who commutes in comfy shoes and brings her heels in a bag. It was a lovely spring day and the company and listening ear was a great comfort. We walked around and around the oval track for about an hour. My friend is an athlete and slowed her pace to match mine. When it was time to go I felt so much better. The thought in my head was that the track is a metaphor for life. It doesn't stop for any one person. It is a never ending loop. You have to keep moving. The best way to do that is to continue putting one foot in front of the other. Years later, when a close friend was widowed, I mailed her clear plastic foot forms. They came with sandals that my daughter (now a high school senior) bought. I tied them together with curling ribbon and wrote ONE FOOT and OTHER FOOT on them. The enclosed advice instructed, "just keep putting one foot in front of the other". It is a universal law.
