I think it's important to look at the sun occasionally and remind yourself that you're nothing more than a useless clump of cells standing on a speck of dust hurtling through space at 66,500 miles per hour.
Take a few seconds. Consider that one day it's going to expand into a giant red ball, consuming your speck of dust and everything upon it. It's as certain as your own death.
Then look back down, smile to yourself and carry on.
