If you ever wonder if you can, as one person, make a difference, then look at this photo.   

The one little rock protruding from the water has created multi-directional ripples that go off and bounce off other rocks creating more directional ripples.  One rock!  

Yes, you can make a difference; but, it requires you to make a difficult choice.  It means that you intentionally go against the flow.  It means that you have to stand out and, at times, take a beating.  It also means that someone may not see the difference that you make.  But, as this photo shows, someone may notice and then tell your story!
