Finding My Voice

I made a goal this year to write one article a week and admit I am struggling.  It has been difficult to find compelling topics that are interesting, relevant, and not just the standard industry regurgitation.  I've also flip-flopped on acceptable categories; should I keep it strictly industry, are personal interests fair game, what about random current events? 

For those who regularly publish content:

• Where do you find inspiration?
• How do you decide if a topic is appropriate?
• How do you keep yourself motivated to write?

Let me know how you approach connecting with the community through your writing.
