A great thing to do for one of the first articles in your blog is to tell your story. Tell people about the industry you’re in, how you got there, and maybe some of the obstacles you had to overcome to get where you are today.
This would also be a good article to include a testimonial. As you illustrate your past to your readers you can tell them about a few of the jobs that you’ve had that had sparked pivotal changes in your career perhaps, sighting specific instances. Adding a story about a happy customer would be a great way to end the article.
If you don’t feel that you have a big story to tell, then maybe ask a few friends and colleagues what they can tell you about you. And if telling your story just isn’t your thing, then keep it short and sweet or just write about something else. Try listing your education, past jobs, etc, like a resume. Maybe include a photo of yourself? It’s up to you!
