1. Use powerful sentences. Aim for shorter sentences with strong verbs. Of course, not every sentence should be the same — you need variation — but try to create sentences with oomph. You might find this easier to do in the revision stage, as it might not be something you’re thinking about when you’re pumping out that first draft.
2. Get feedback. You can’t get better in a vacuum. Get someone to read over your stuff — preferably a good writer or editor. Someone who reads a lot, and can give you honest and intelligent feedback. And then listen. Really try to understand the criticism and accept it and use it to improve. Instead of being hurt, thank your editor for helping you get better.
3. Put yourself out there. At some point, you’ll need to let others read your writing. Not just the person who you’re allowing to read it, but the general public. You’ll need to publish your book or short story or poem, or write for a publication. If you’re already doing a blog, that’s good, but if no one reads it, then you need to find a bigger blog and try to submit a guest post. Putting your writing out in the public can be nerve-wracking, but it is a crucial (if painful) part of every writer’s growth. Just do it.
4. Learn to be conversational. Many people write too stiffly. I find that it’s so much better to write like you talk (without all the umms and uhhs). People relate to it better. It’s not an easy task at first, but it’s something to strive for. And that brings up another point — it’s better to break the rules of grammar in order to sound conversational (as I did in the last sentence) than to sound stilted just so you can follow the proper rules. But don’t break the rules of grammar without good reason — know that you’re doing it, and why.
5. Start and end strong. The most important parts of your writing are the beginning and end. Especially the beginning. If you don’t hook your reader in the beginning, they won’t read the rest of your writing. So when you’ve written your first draft, spend some extra time crafting a good beginning. Get them interested and wanting to know more. And when you’re done with that, write a good ending … that will leave them wanting more of your writing.
