How can you write regular, interesting blogs?

Yes, how do you? This is a genuine question. How can you keep up regular, interesting, relevant content on your blogs that you can then translate into promotion on your social media channels AND that ties into your larger marketing campaigns?
 
I have the theoretical answer, at least. With enough time, manpower and money, planning and executing your blogging schedule is easy. I do find that if you pay for someone to write your blogs (or in my case, I am the person people pay to write their blogs) that gives the motivation to come up with topics, to get them written up and to get the blogs published on time.
 
However, when it’s your own blog you’re struggling on… it’s never that easy. Maybe it’s missing the third party objective view on what is interesting, what needs to be explained, what’s a trending topic. It might even be the temptation to put your blog to one side while there are other more pressing matters to work on, like actually running your business.
 
After very nearly completing my 30 day blogging challenge earlier this year I do know how effective regular blogs are. Impressions, webhits and enquiries rose for my own site through nothing more than me rambling on about a few marketing (and non marketing) topics. But still, after I had given up on the challenge, I still didn’t carry on doing regular blogs. Life and work got in the way.
 
When I did sit down to write my own blog, I couldn’t think of a good topic. I felt like I had done everything before. It’s a very easy cycle to slip into, and one you should be prepared for when you are marketing your own small business.
 
So, how can you break this cycle? How can you write regular, interesting blogs?
 
The answer, of course, is to write about the thing you are struggling to write about. Then throw in some keywords. Marketing! Social Media! Marketing Consultant! Newbury!
 
I’m going to try and put together a blog every week from now on – if there’s a topic you’d like me to cover (it can be marketing, or why I feel the need to dress like a five year old, or the best place for a jam doughnut in Newbury, whatever you want) – contact me and let me know
