To make a poem is simple
All you need is

Nights of tears
A bit of blood
A lot of pain
A touch of peace
Heaps of feelings

All you need is

Pure exhaustion
Fear
Anger
Love
Sadness

All you need is

A whole load of
Emotion

Then when that explodes
Out of your body
You just need to somehow direct
All of it onto
A piece of paper

That's how you make poetry
