You shouldn't put yourself down so much. We become who we think we are; so let's think we're better. Fake it until it's real is the surprisingly insightful phrase that would sum that philosophy up, I realise.
If it is not something you desire to do.. then don't. I just wondered because you seem to be experienced at writing, and I thought it a minor possibility that you may simply be lacking in ideas, in which case I would have given you some if you had wanted. But, there's nothing wrong with short if that's your thing.
