It can be scary, putting yourself out there. Sharing with the world something you created. Because when you do that, you’re leaving yourself vulnerable. Open to criticism. To ridicule, even. No one likes to be embarrassed.
But if you’re of a creative bent, there’s little choice. Yes, you can create things just for yourself. Horde them like Scrooge McDuck, and open the vault once in a while to play with your darlings. That’s a lot safer. But not very satisfying.
We create is for ourselves, but we also create to communicate with others. That communication goes both ways. We communicate with the world via our art, be it writing, illustration, sculpture, acting, sound design, or what have you. And the world communicates with us in the form of criticism, praise (if you’re lucky), or indifference. To say nothing is to speak volumes.
For those of us who write, many began their journeys in one fandom or another. Yes, I’m talking about fan fiction. It’s an attractive place to start because the characters and setting are already established, leaving you free to focus on story. You might also find yourself cultivating a number of friends in the community who support you while you support them. But to make that first step, to post your first fanfic, that’s a hard thing to do. After all, not everyone online is supportive. In fact, there are plenty out there who seem to thrive on spreading misery. They are to be ignored. For what it’s worth, in my fan fiction experience, I never had haters, just supporters, and I count myself very fortunate .
As you grow as a writer, with practice and with the support of your writing community, you might find yourself branching out to original fiction. Or not. We write, after all, for the love of it. There are, at the time of writing, about 76 thousand Doctor Who fan fics posted on FanFiction.net. Several tens of thousands more are posted on archiveofourown.org. There are sites where you can post original fiction and interact with community members of similar interests. Examples include Wattpad and Inkitt. You can also go the self-publishing route if you’re so inclined. I happen to know at least one pretty good self-published book …
This is truly the golden age of creative output. With the tools we have readily available at home, we can easily create all manner of works and make them available to others. And you never know what will come of it. Anyone remember this tweet from Emily Cook?

After organizing this event, plus a number of others, as well as producing outstanding extra content from Doctor Who alumni, Ms. Cook is now a Big Finish producer. Jonathan Carley, who put himself out there as, among other things, an interpreter of the War Doctor, now has two Big Finish box sets in which he has starred. Jaspreet Singh, who has produced, edited, and sound designed a number of Doctor Who fan productions (including my personal favourite, Doctor Who: The Eighth Day), has been doing editing and sound design work for Big Finish. (He also does a pretty mean Third Doctor.)
Let’s be honest. Commercial success in the arts is hard to come by. So while it’s fine to hope for that, don’t make it the sole driver for your output. Create what you create for the love and fun of it, and if nothing else, you’ll be making the lives of those around you a little bit brighter, which is perhaps the greatest success of all.
