It's easy. I just remind myself that, in about 5 billion years, the Sun will have sufficiently run out of fuel to begin its transition to a Red Giant. At that point, all remnants of biologic life that ever lived on the crust of the earth will be incinerated and it won't have mattered whether anyone carefully conserved the precious time remaining in their lives or not. I have so thoroughly incorporated this understanding into my psyche that I can merely blink now and all of that context is immediately present to me.
