Take your most popular tweets and FB posts, or the ones you feel most passionately about, and use them to develop blog posts. You don’t have to write three pages; you don’t even have to write four paragraphs. Seth Godin is one of the most successful bloggers in the marketing world, and he writes in two- to three-sentence paragraphs. He’s a master at expressing ideas that are thought-provoking and easy to read. People are time pressed these days and content can be overwhelming, so make it valuable and easy to read.
Another way to get ideas is start commenting on the things you read, such as other people’s blogs and newsletters, media publications and anything else relevant to your business. You’re already absorbing the content and you probably have opinions when you’re reading it; go ahead and comment on those blogs. One benefit of commenting is that people will start recognizing your name, another is it gives you material for a blog post.
For example, I save the comments I write in my email Drafts folder. I use the subject line as a label for the topic. After I’ve saved the drafts I can come back and turn these comments into blog posts. I can even make the comment itself the blog post. After all, it’s still my writing.
