In the grand scheme of things, most of us like to think we are more important than we really are - that we matter more than the next person, that what we do, say, think, want, feel, etc., somehow takes more precedence than what someone else may do, say, think, want or feel.

Think again, as you ponder this picture. See that little bluish-white blob about this big - . - down near the bottom of the page? That's the Earth, from Mars, actual size. That even tinier white blob just below this sentence -  .  - is the Moon from Mars.

So, how important do you feel now?
