Writing is not my forte, so I will point you to some great writing resources.
http://www.wikihow.com/Write has a comprehensive list of the steps to writing well. I look at the list and think really? All that? But I also know that writing takes effort and great writing takes even more effort, so really. All that.
No, I didn’t follow all these steps with this blog post, but I’m guessing you already knew that. One day I’ll write you a thoughtful and well-worded essay on a subject I know. Just to prove that I can and thereby show you that you can too.
For an overview and to hear from writers head on over to http://www.bbc.co.uk/worldservice/arts/features/howtowrite/index.shtml
They write about how to write fiction, but most of it will apply to all writing.
Reading increases your vocabulary, and exposes you to other ways of thinking and seeing the world. Reading exposes you to the good, the bad and the mediocre of writing. Reading makes you aware of the written word.
Tips I try to remember
