Edward Everett Hale once wrote these words about the power of one: I'm only one,

But I am one.

I can't do everything,

But I can do something.

What I can do,

I ought to do.

And what I ought to do,

By the grace of God

I will do.

Never discount the power of one.  If you set your will to accomplish something great, to make the world a better place in which to live, it can be done.

And remember too: if you can find some others to engage with you in this endeavor, the world can be changed!  But it begins with you, one person, with a great dream to make this world a better place to live.
