Sorry for your loss. Not from HGG but here is what I love.

From Thich Nhat Hanh.  

When we come to grips with our mortality—and realize that we aren’t going to live forever—the preciousness of everything in life emerges from the depths of our minds and our experience of life changes significantly.  If you’re anything like me, you might have moments when you get reminded of your mortality—when you are touched by an emotional scene in a movie, or when you pass by a car accident, or when a loved one gets sick or dies—and after you spend some time feeling sad, upset, or philosophical, you go right back to living without death in mind and unintentionally live taking life for granted.   

And while I don’t think that we should live with death always on our minds, I think that finding ways that we can remind ourselves of our impermanence on a daily basis can definitely have positive effects on happiness in ourselves and others. When we carry mortality around in the forefront of our minds, life becomes increasingly precious.  We see what we may never see again; smell what we may never smell again; hear what we may never hear again; touch what we may never touch again; and taste what we may never taste again—and we enter a blissful state of deep gratitude and appreciation for what we have in each moment of each day.
