Which word better describes you?

I am not like the water which flows along the rocks
Or the blood that fills my veins with apparent "facts"
I am not the potion that you swore you drink
You made them turn around me, doubt, and think

No I am **not that.

I am the dirt that fills my very inch
Because if you ever see me I promise to never flinch
Because in spite the fact that you did that to me
I will stay my own canvass and portray what I should really be
