Reach out to, spend time with and hold those you love. If you can not hold them because of COVID-19 then look them in the eyes, be deliberate, go slow and say "I love you". Spend time connecting and being explicit about what you love in them. Do not let a day go by without loving.
When you have the ability to be with someone in person or virtually give them your full attention. Listen without interruption. Turn off the phone. Turn off all other media and outside stimuli. Be present.
Give yourself time to focus on your own health and well-being. Appreciate the sunlight in the morning. Get up and be thankful. Review everything and everyone you are grateful for having in your life. Take nothing and no one for granted. Stretch, do yoga, meditate, pray, walk, run, swim, say hello from 6 feet away. Learn to like yourself. Be in nature and express creativity.
Be of service, somehow to someone. If there are elderly in your neighborhood, take out their trash, cut their lawn, trim their trees. Help others and allow others to help you. Renew your sense of purpose and make a contribution.
