I Used To

I used to believe
in the good in people
and I used to think
that my mistakes don't count
in the enormous universe
that a person this small
couldn't make any difference
not good, not bad

I used to rely
on mere words
which didn't even need to mean anything
and I used to think
that promises are the glue keping this society together
I thought I could find forgiveness when needed

I used to do so many things
and kept the apocalypse far away like that
It was so harmless
to be innocent
But now my mistakes are everything
people can see

Are they all that defines me?
