You know those scenes in movies where they start with focus on a particular thing and then "zoom-out" until you can see the entire Universe? Well you should try that. Only don't think about the scene (as I usually do), but focus on yourself.

Start by picturing just yourself. Then Jump back until you can see the building you are in, then the city you are in, and then the country you are in. Remember to focus on where you are. Now imagine where you are in the Solar System, and then the Milky Way, and then the Universe.

Trust me, if you do it right it's an interesting experience.
