This is not about being a blogger — that’s the matter too complicated to be addressed now, no. This is about advantages of running a blog, which are not so obvious for people, who have not tried themselves.

• Improves self-consciousness and helps to concentrate on things that matter.
• DRY principle. Comes from programming and suggests that you Don’t Repeat Yourself. It helps a lot to provide a link to your opinion on the matter if you have once made it a solid post. You can express yourself as thoughtful, as you want to one single time and then update it, if your opinion changes.
• DRY in sense of sharing some stories with your friends. You won’t need to retype or describe any vacation or journey, once you’ve written a post.
