Fear keeps us focused on the past or worried about the future. If we can acknowledge our fear, we can realize that right now we are okay. Right now, today, we are still alive, and our bodies are working marvelously. Our eyes can still see the beautiful sky. Our ears can still hear the voices of our loved ones. Thich Nhat Hanh
