Broken dreams

I wrote a short something (I really don't know what to call it) about dreams (surprise!) for my english class. Tell me what ya think.
Road of broken dreams
A dream is like air we breathe, 
we need it to survive.
Because if we stop dreaming we won’t be happy anymore.
A dream puts smile on our face,
gives purpose to our lives.
But there is always a time in our lives
when we need to decide what do we want to do with those dreams,
are we going to make them happen,
o are we going to leave them to die on a road of broken dreams.
