Watch what you're doing
Listen to what you say
How would you feel
If I treated you that way

^This opening stanza here starts off with a warning and that would want to make the reader to read on...good.

Take a step back
Breathe in and then out
Use your words
But don't scream or shout

^Sounds like the writer here is giving tips to control one's anger rather then using an angry tone with volume!

If that doesn't work
Try counting to ten

^My grandmother used to tell this to me..reading this brings back memories :)

Don't speak before you're ready
But when you are, try again
Don't act like a boy
Because I know you're a man

^Good advice here for the writer tells the person to behave like a grown up rather then a child who does not know how to control.

Before you lose it all
Turn your fists into hands

^The ending is good. It calms an angry soul to unwind from a battling position and to use words..good write :)
