My primary focus at this stage is audience. I want as many people exposed to my work as possible. I want to start establishing a reputation in writing (in preparation for a future shift to writing as a career, perhaps ten years in the future).
If you are looking for exposure for writing, then you must be prepared to start your writing career today. Especially if you want that to be your sole support of income in ten years. If you really want to write, I would suggest getting a copy of Heinlein's rules for writing for motivation. These were in a recent article in Deep Magic e-zine. To sum up, out of 100 people who say they want to be a writer, only two or three will keep at it until they are published.
To get your name out, I would start by submitting stories and articles to some of the e-magazines that are mentioned on EnWorld, specifially Stygian, since they are currently needing submissions. I would also try Deep magic, ENWorld journal, D20 weekly, Asgard, and any other you can think of. Be warned, you will get many rejection notices, but keep trying. If you do have a story bought by a magazine, remember that in many cases it will not be published for many months. In other words, if you are looking for name recognition, it might be six months for your first story to be published if you sent it out today. In many cases it could even be longer. In four or five years time, hopefully you will be putting out the type of work and had enough stories published that you will be moved to the top of piles by editors.
If you need some help on how to do this entire process, I would again recommend
www.sfwa.org/. There are several articles there that would be helpful to a beginning writer on how to submit stories and common mistakes that writers make. The main advice that they all mention is to write everyday and read as much as you can. If you can't find time to write today, then you probably never will (Heinlein's first rule).
Anyway, I hope this helps some and good luck.
