In order to be a successful blogger, it is important to be well organized. One of the things that will help you be organized is to devise a daily plan of work. Here is an example of how your plan of work can look like:

-Check and reply to comments. It is important to maintain a bond with your readers. Your visitors are going to appreciate that you care about their opinions.
-Read email, and take action. This might include responding to an email, registering somewhere, forwarding emails, etc. It is not a good idea to skip this step as you never know what email you might receive.
-Visit other blogs that will help you decide what you want to write about, and see what is happening in the blogosphere. You may want to suggest link exchanges with other bloggers, or get involved in a discussion.
-Write and publish your post. You may not need to do it every single day, as it depends on the type of your blog. It also depends how dedicated you are and how much time you have.
-Market your blog. There are many articles written on this topic, so I am not going to go any deeper into that right now.
