Who Am I?

I am an elitist

I have trouble meeting new people and making friends

I do not speak for myself

I have trouble working in a team

I am unable to contain my ego

I came desperately close to winning my dream job

I stabbed my last two bosses in the back

I have fallen out with my entire parliamentary group

I skulk in the shadows

I inadvertently display authoritarian tendencies

I am consumed by bitterness

Who am I?
