Do you have the title gene? If you don't, get help from someone who does when deciding on your final title, so you can find the title that will work best for your book. Personally, I love playing around with titles to make them stand out a little, and increase their chances of sounding interesting enough to grab the attention of potential readers.
Speaking of trying to improve how something reads, and how appealing it might be to potential readers: Check out this post on how to give your narration flavor, and this one on how to instantly add depth to your story. Also, here are some tips on where to start and what to consider when it comes to world building.
Of course, all that adding depth and stuff comes after your first draft is completed. When it comes to your first draft, you should always ask yourself the question, "What would you write if no one was looking?"
Speaking of your early drafts, this post on how to outline by the seat of your pants shows a great way to find a balance between writing with an outline and avoiding using one. Actually, the method isn't all that much different from the one I use to write what I call my rough drafts, though I've never thought of it as an outline myself.
Regardless of your method of writing - and regardless of what it is you're writing - remember to edit when you're done. Everyone makes mistakes; even the best editors can sometimes miss something. Do all you can to avoid letting those typos and grammatical errors slip past you though. Remember: If you don't care about grammar, you don't care about writing.
If you're having a bad writing day - which, let's face it, we all do from time to time - you should read the first of the two posts I'm linking to in this paragraph. There's some cursing in the post, just so you know, but it's a great reminder that having a bad writing day - or several of them - is something that happens to even the best writers. Always remember not to underestimate the importance of mastering the art of taking a break!
By the way, do you want to connect with fellow authors on Twitter? Or, perhaps, you just want to make the best use of hashtags to promote your own book? Either way, check out these author hashtags for Twitter.
Speaking of marketing and promotion: Have you considered Finding peripheral sales channels for your book. If not, you probably should. Either way though, check out the post for a few tips on doing so.
Also, if you work from home, here are five rules that will help you work more productively from home. The article was officially written for those who work from home by being paid for blogging, but could apply just as easily to any kind of situation where you work from home, including - but not limited to - the writing of other content besides blog posts.
