I don't really know of any other way to make things up. There are some days I want to write 10 blog posts, some days I can't think of anything to say. Either way, I have committed to showing up every day in order to write something interesting. Some days are better than others. It certainly hasn't gotten any easier. I would like to believe I'm a better thinker than I was 2 months ago when I started. I'm also pretty sure I can type faster.
My big learning over the past two months: we're all just making it up as we go.
