This one is the physical underpinning of the whole model — there is nothing outside of nature. Everything is made up of atoms and the space between them.

This quotation has become my mantra. It reminds me of two things:

1. the atoms that make me up are going to disperse at my death and I will no longer exist; and
2. this experience of consciousness that I am having is incredibly wondrous.

I say it whenever I am in distress to remind myself that in the end the current context will go away, and to ask myself, is this how I want to spend the time I am given?
