Personal extended metaphor poem

I am a book
Im not always accurate
But I have a story of my own
Many people walk in and out of my life
They may judge me by looks, personality, actions
No facts are told
They’re just characters that complete my endless story
I can be interpreted in many different ways
Which can affect each and every page of my life
But that makes all the difference
I’ll be on the shelves
On the best kind of wood
That would support
My theme and my message
Because every book has an author
She knows herself well
She writes what she loves
