I agree with Karen, I just recently re-vamped my categories and menus to do just this.
For something like a misc. post, if its something your passionate about, that really is about you, I would add a category that is just about you as a person. For me, I have changed my original "Mommy side" menu to "personal & family life" with my "personal growth" subcategory being the about me posts.
I then, chose to add in "parenting" (all things related to actually raising the kids), "the mommy side" (specifically for those things that are about being a mom - like taking time for ourselves, asking for help and other more specific mom issues) and "faith" (for those times I want to discuss my faith, and raising my kids in faith).
I hope this helps, good luck and I can't wait to read more.
