What Makes Up A Good Blog

In starting this blog, I have to ask, What amount and kind of content makes up good blog? My goal is for it to define me as a familyman, and professional. It should be about what interests me. That being technology, family, books, & thoughts. I believe that it should reflect the balance in life in which I do all of those things. For me, about 50% of my time is consumed by technology, 30% is enjoying family, and remaining 20% is split evenly between books & thoughts. Hopefully, my content will be worthy of following. Let me know if I need to include something else, or add/remove anything as I’m sure this will be a rough draft for content composition.
