Book excerpt: As the COVID-19 crisis took our world under siege, essential workers worldwide kept their heads up and extended their hearts to keep us safe at home. From our neighborhood mail carriers and grocery store cashiers to the truck drivers, farmers and manufacturers who make essential goods available to the millions of us around the globe, we say THANK YOU! You've kept our bellies full and minds at ease. We love you for all that you've done and continue to do for us every day.
