How can I improve this poem?

I wake up at 5 a.m.
I put on my jump suit full of different scents
Holes are my friends
Garbage is the enemy
No one gives me a simple thank you, or a friendly smile
They look at me as an illiterate, dirty man
They know nothing about me and I know everything about them
I know when you party, bottles, napkins, cans all scattered for me to pick up
I know what you got for Christmas, or when you welcome a newborn to the family
I can calculate your cashflow and your character by the cleanliness of the cans
But it wouldn't matter to you because to you I'm from the land of garbage men
I think of the world without me, a muddy and stinky pig pen
How would you live? Probably decay before the week is over
Kids throw their water bottles at me and say "take this with you"
I am not the trash can I yell, but know my words will not change anything.
They would rather listen to their dads snoring then to talk to me
I deal with the loud engine, the squeaking of the tires from my garbage truck
But all you can do is complain about it, 'they tell me to "shut if off and leave"
I say fine, the garbage can pick it self up my sanitary desires are not welcome here
I'll leave the waste here and pray for this place to be buried
How can I add simile, hyperbole, personification, verbal irony, alliteration, and metaphor to it?
Any help would be appreciated!
