Hello @phelimint,
I understand you. I think what to blog about is getting had for everybody but we just have to search deep into our hearts and something to blog about will always come out.
Also from time to time even when you are not on steemit, some ideas of what to blog about might come to mind, it would be nice to write it down somewhere, so that anytime you run out of ideas, you can go back and use it.
This is what is helping me so far.
