Hi Glenna! Hope you are well and glad you asked. We like personal stories. They need to have application to the reader's lives. And it's easy to add an external source. Here are a few examples: https://medium.com/publishous/every-parent-knows-the-job-of-parenting-is-a-lifetime-sentence-95f2900c650a?source=friends_link&sk=1ead75e1408f0d254b2e18d4a94424e0
