You create something. Simple as that. But not just anything- create something that inspires controversy, heart ache, or adventure. Scare people, mystify them. Then publish it. But the publishing process is sort of really really difficult, yeah? Yeah. So you can publish it to kindle! People would be able to download your book to their phone, tablet, or kindle device (obviously) by buying it on Amazon. This process is extremely doable- I've already done it twice. smile
Now that you have published work, you advertise it. Create a website for it, use something like freewebs.com. This is an excellent, professional grade website-creator for which you can pay extra to remove their domain. Your site would appear, Mysite.webs.com, paying takes away the ".webs." but that doesn't really matter for now.
Now keep creating spaces of yourself on the internet. Youtube linked to your website, twitter linked to your website, facebook, foursquare, whatever- just keep making accounts and profiles on every possible network under your author name, or even the title of your single published work, though this could complicate being discovered when people know you for many titles in the future.
Now you exist on the internet- but will people find you? Hashtags don't just exist at the end of status updates- they're everywhere in their own varying forms. They exist within pages, and that is how we google things. We are just looking up keywords to things that exist somewhere on the internet. If people look up keywords in your website, the name of your book, or your name, chances are one of the many spaces you inhabit on the internet will surface in their engine search.
Next, become a virus. send e-mails, texts, and messages on social networking sites to every single person on your lists, even if you don't even remember who they are, or it was an accidental ad- send it to EVERYONE. For all you know, someone's interest will spark. Talk to enough people and your bound to get interest. If you tell everyone and encourage everyone you know to tell everyone they know, word will spread very quickly. Tell your parents, and they'll tell their company and those people will tell there families, and those family members will tell their friends who will tell their family and so on. Push it like drugs, man.
Talk about your twitter on your youtube and your youtube on your facebook and just advertise advertise advertise. Visit other twitter pages and facebooks dedicated to similar subjects located in your book or poems or whatever you've published, and advertise THERE. Retweet other famous authors, and when people are looking them up they'll see you. Just circulate. And if people like what they read they'll tell people. That's how everything works. But you have to CREATE something first. The more you create, the more you have to represent yourself, the more justification will lie between your advertisements. you have to love what you've made and you have to believe that it is a valid use of others' time to read your stuff.
People are what will drive you, and if you love it and you want it, you'll get there. smile
