Decided to go through all my posts today and add labels to each one for easier searching. For each post, I added at least one label whether it was "personal" or an "explanation". Then I added additional labels, depending on the content. I then added a gadget to the right column to show all the labels. So, if you want to find all my posts relating to "medical", for example, just click on the word "medical" and my blog refreshes to show posts about the medical. Hope this helps!
