The antithesis

I'm not a hero. I'm not called to save the day.
My joys are ordinary. So are my sorrows.
My needs are simple.
My battles; my victories; and my defeats -
All routine. All run of the mill.
My interests are few. My passions, fewer still.
I know some facts. Opinions - not many.
My weaknesses are typical, strengths normal, if any.

But, I am.
Like the basic definition of matter - I have mass and occupy space.
And for that reason, I matter.
