The business of writing is more complicated than just penning a novel, a collection of poems, or a collection of short stories and then publishing. First collect test readers to help you feel out the material, edit the book professionally, find an agent to represent you, and then possibly garner a publishing contract from a publishing house. The better representation you get will help increase the chances of a bigger contract. Some agents take only referrals, others accept solicitation.
If you are a rebel and want to join the new age, look into self-publishing your work. This seems daunting, but achieved by thousands of new indie authors every year. The process is unique and not as convoluted as traditional publishing. You are in charge of the whole shebang from writing to publishing and you can do it cheaply.
