I do like how your posts have become more personal and more from your perspective as opposed to "research" or too factual.
Maybe you could try some guest posts or co-authored posts. It would give you the ability to have a break from time to time, but still keep your blog up and running. Plus if you had topics that were interesting to you and you thought should be read, then you don't have to feel as if you aren't qualified enough to write about them, because maybe someone else could, or at least help you. Personally I don't like huge amounts of guest posts, but one every so often is nice.
