kicking puppies is bad

I try to do good things, but generally I have very little impact. Someone way smarter than me did something very cool: http://www.pimpthisbum.com.

I wish I was smart enough to do something that actually had a large measurable positive impact on the world.  I sometimes feel like the things I do to make the world better have very little impact.  The girl I tutored still had to repeat first grade.  Is she better off?  I don’t really know.  I mean, I clearly didn’t turn her into a rocket-scientist, a brain surgeon or Noam Chomsky.
