Categories and RSS feeds offer a quick access to the site contents and, if you like, adding the feeds you like to your site. Although most of my posts are somewhat related to each other, I write on a variety of subjects. All the posts fit at least in one, sometimes more than one categories. They help me organize my writing and help you find what may be of greater interest to you.
By following the category links you may view all the posts that fall under that group in reverse chronology order. I have also RSS feeds for each of the categories which you may put on your site if you like. It is a simple process, at least in the WordPress world. Below you will see the categories with an RSS icon next to them. Click on the RSS icon which will open in a new window and show the recent posts under it. You can copy the link from your browser, add an RSS widget to your sidebar, footer, or other widget-ready area in your theme and paste the feed URL into the appropriate field. After saving the widget you, and your visitors should see the most recent posts added to Mostly Happy Journey as a listing.
