Welcome to Hubpages!
Unfortunately, I have found that the (next) topic to write about always comes from within and I don't know what you have within. I did notice (from your profile page) that you have answered a number of question which would suggest you have an interest in those subjects...perhaps you would like to create an article about those answers?
Additionally, Hubpages offers a Weekly Inspirational Topic that might match up with your interests. In short...write what you know and write what you love! I look forward to your first effort!
