I tell other cancer patients to do something good for somebody every day,” Marelle said. “It doesn’t have to be big—it can be as simple as opening the door or saying good morning to someone. If that person says good morning back and tells you how he or she is doing, listen to what that person is saying. It took me having a setback with cancer to realize that I haven’t paid as much attention to other people as I should have. And as I started doing things for others, I realized it was giving me strength to do more for myself.
