One option that many people don't think about is to use an article template. An article template gives you a general idea and then you have to insert the topic using the idea they suggest. For example an idea would be Methods for Saving X and a topic would be Methods for Saving Money. With most templates you will have the ability to do at least two articles from it until you can come up with more topics. The two articles would be a positive and negative or upside and downside. There are a number of places you can visit for article templates. Some of them supply free templates while others charge a fee for them. You'll want to do a Google search to see what you can find and use for your articles.
Article templates can also help you with your blogging. No matter where your writer's block is at a template of some sort will help you get through it one way or the other. You may look at the template and say, I can't write anything on that, but this one came to mind instead. Article templates are a great way to get yourself over a hump in your writing or they can help you come up with even more topics to write on. When you have writer's block you need to remember the traditional ways to come up with topics and then them about article templates.
