The next step is to put some time into designing your blog, and that means heading over to the Template Designer. There are two ways to get to the Template Designer; go to Layout and then click the link that says Template Designer, or go to Template, and click "Customize".
Once you're there, really take the time to choose a good template, and remember that within each "style" are multiple templates for you to choose from. For example, you can see in the photo above that the Awesome Inc. style has six different templates to choose from.
Once you've finished designing the template you can then move on to creating an "about me" page, designing a header that is custom made for your blog, and then maybe writing some posts.
