1. Write notes. Lots of them. When you think of a good idea and write it down, you'll often think of what you want to say, points you want to make, etc. If you don't write those down, too, you'll lose some of them. So make notes under your idea – it'll jump start the writing process for you.
2. Write for extended periods of time. The first hour of writing tends to be the least productive for most people. Then over the next 3-5 hours you should be in the flow of writing until you eventually get tired and need to quit for the day.
3. Write simple. Bullet points and numbered list types of blog posts tend to write themselves.
4. Write about what you know about. Hopefully you already know a good deal about your topic – if not, research it before hand.
5. If you're having trouble getting started, write nonsense and gibberish until your mind gets into the flow. Often this takes only a minute or two. There is no such thing as writer's block – only writers who won't start writing. So write anything and when you mind is ready, you'll find you're writing about your topic.
6. Write somewhere else. Most writers find they are actually more productive when they move out of the office and into the local coffee shop or park bench.
7. Make writing a habit. Just like anything else, the more you do something, the better you'll get at it.
8. BONUS TIP: Would you believe that you can write faster by hand than you can by typing? According to author Karen Dionne, when she had an impossible deadline looming, she turned to handwriting her chapters and found she could write 3,000 to 5,000 words per day, rather than her usual 2,500 words per week.
