You are who you are

The trouble is
you are who you are
I wish I was someone else
but I'm not
I wish I were sophisticated
I wish I was educated
I wish I were successful
I wish I was someone
that someone else might admire
but I'm not
I'm just who I am
and this is gonna have to do
but more important
I wish I could work out
when to say
were
or
was
