For some people it might be difficult to start writing many articles. Due to this they might be afraid to set up their own blog. I recommend that you at least try to set up your own blog, because it is not as difficult as it sounds. As a blogger you need to post on a regular basis, but keep in mind that they articles you write can be quite short. The important thing is to blog on a regular basis, but it is not that important to write a wall of text. As long as you write on a regular basis, the article length in not that important.
