Blog posts don’t always flow beginning-to-end in a single smooth, elegant effort. Your kids interrupt you. The dog needs walking. It’s almost midnight and your train of thought has long since jumped the track.
Or maybe it’s a good interruption, e.g., the ice-cream truck or the UPS guy. Perhaps you promised your partner you’d go see the Metropolitan HD broadcast of “La fille du regiment” and it starts in 30 minutes – do you want to write until the last possible second, or do you want to build in enough time to get some kettle corn?
Of course you want kettle corn. You also want to blog. So I suggest you do what I do: Quit.
