Having worked in PR for most of my 25 year career, I've written countless articles, press releases and case studies on behalf of my clients.  More recently, I've written guest blogs, along with generating ideas for Twitter posts and am frequently advising clients on how to make sure they follow a structured approach to subjects they're keen to blog about.  So when it came to writing my own blog, I thought the words would flow and I'd have a multitude of subjects that I'd want to talk about - and then my mind hit a wall - it went blank.
