So I;

I move in the same pace as the river.
I flow along with it as I keep a shiver;
Ignoring all the rocks that come my way,
so never will I be in one place to stay.

Yet you;

You struggle against the fast moving water.
You flow against it with a sturdy little quiver;
Using the rocks as so to keep you at bay,
then breathe a sigh of contentment and stay.
