1. Consider your audience
Even if your blog is generally personal, still, it would be better to consider the minds of your readers. You have to think of something that would interest them.
After all, most of the reasons of people who write blogs are not at all confined to their own personal motives. Most of them would love to be “heard” (or read) and would love to be known, in some way or another, even for just a minute. So, it is very important to come with a write up that everybody can understand, not necessarily that these people can relate to it but they can understand it.
