The world’s become a little too mean

Sometimes I wonder about people’s intentions.
Are we placed on this earth ultimately to be selfish?  Or are we here to be there for our friends and family?
I don’t know what I am saying.  These things pop into my head when I’m observing at school, and at work especially.  I encounter so many selfish people, and just when I’ve about given up on the good of humanity, there’s one beautiful selfless person whose energy is so radiant that it pretty much leaves my initial assay of the uglies in a complete blur.  Almost as if they didn’t matter in the first place.  People like that make me smile.
