I frequently have all of my work completed, and I am unfortunately not allowed to work from home. This means I spend a lot of time sitting at my desk scrolling social media, because there’s nothing that needs done. I feel like I’m wasting my time, even more than work already wasted the best hours of the day. How do you fill that downtime with something that is personally valuable, but not disruptive or noticeable enough that you’d get in trouble?
Never think of your writing like that. Remember that both Twilight saga and 50 shades of grey exists as best sellers. Your writing is clearly better than that (just from this post!).
Consider something like Smashwords, or even sticking it on Amazon for free/cheap. You may not be the next Tolkien, but you worked on the book, let people read it!
