As long as you have a subject in mind writing these Hubs is not always a bad thing. I have a few personal experience Hubs up. Some are funny, some are inspirational, but all of them have a definite topic and point. They don't ramble on about nothing which I think many blogs do. Find a topic where you know you can offer help or comfort to someone.... have you survived the loss of a loved one? Lived through a traumatic event? Learned to live with an illness? Had some sort of great epiphany? Then you might have a story that is worth reading. Good luck!
