I am a pawn.

I am a pawn.
In the game of chess, pawn is the weakest piece.
It is often used metaphorically to indicate unimportance or outright disposability.
Today, I'm merely a pawn in the game of life.
The name origin of most chess pieces is obvious.
But the pawn's meaning is fairly obscure.
Pawn is often taken to mean
"one who is easily manipulated"
or
"one who is sacrificed for a larger purpose".
That is totally me.
Stupid chess.
