I'm not affiliated with medium at all - it's just the easiest way to get started blogging (in my opinion), and it's what I use (I cross post this blog to medium).
Basically - I say that if you want to be an independent consultant, you should start a blog and write at least three posts as a way of demonstrating that you're an expert in that area.
I guess you're right about the three vs one though - I should make that more clear. I used three because it's the number I give in the "First Client Checklist": https://www.breakintoconsulting.com/first-client-checklist
