The thing which makes blogging difficult is not engagement, analytics, finding just the right theme, curating to a newsletter, managing comments, finding reach after the demise of Google reader, etc.
The hardest part is showing up, every day, writing. The hardest part is writing! The second hardest thing is hitting the publish button on a regular basis, not necessarily every day.
Deciding what to write about is pretty tricky too. And not falling prey to "hmm this idea really deserves a nine-part, 15 thousand word treatment, probably in eBook form". And hitting Publish
even when you're not sure.
So I'm trying to blog (most/many) days in November. Which is easier than writing a whole book! The roadblocks look pretty similar, though.
