Blogging limits

I’ve been blogging for quite some time but have always set certain limits for myself. I notice the posts and blogs I enjoy the most contain true to life personal stories and information. I write about all kinds of things, sometimes I even earn money for writing something. In trying to improve my own writing skills as well as have an enjoyable blog I recently decided to expand my limits a bit. That’s left me wondering if you as a blogger have set limits for yourself on what you’ll blog about from your personal life. I don’t mean the acne treatments and the common cold, I mean the real stuff. Where do you draw the line on what’s ok to write? What’s the most personal thing you’ve written about?
