I like to write about things I'm already thinking about. I was a solid B student when it came to anything regarding writing, and I think that's because I hate writing about things I don't care about. My brain goes from "Articulate Thought" mode to "Do the bare minimum" mode as soon as I have an obligation to write something for someone else. I'm by no means a perfectionist, but when I publish something I like to at least be proud of my work.
Hopefully, when I have more time I can write coherent posts more often. For now, my Startup takes the vast majority of my time, so I'll only site down to write when I feel a very strong urge to do so.
