The problem with having a blog is it means adding another item to your to-do list! I used to diligently write blog posts regularly for a previous blog but lately find myself too busy.. Now that I keep a running commentary of news, thoughts and activities on Twitter it’s harder to take time out to pull a blog post together. Also I may already have written several blog posts that day in a ghost writing capacity and feel it’s healthier to escape my screen for a while, get outside, run around and absorb some vitamin D 
Conclusion: Must practice what I preach and try harder!
