Best advice I've heard for getting started is...
Write, write, write, write, write, and then write some more. Find places like HubPages to get it out there so other people can see it and you can get feedback. But write, write, write and keep writing!
Then, while you are writing, define for yourself what you consider to be 'successful'. You will need to know what you are aiming for before you can take aim.
One more thing, based on reading your profile, I would say learn to break up your writing into smaller paragraphs. Unless you have a really compelling writing style, your readers will find it bothersome to digest such large paragraphs.
Good luck! =D
