No. There have been times when I haven’t been confident about what I was writing; times when I’ve had no clue about how to continue something; certainly there’ve been days when I haven’t felt like writing and even a few days when I’ve felt like I’d already written my last thing, ever.
These are all tangible problems with workable solutions. I can deal with tangible problems. If I were to believe in “Writer’s Block” I’d be taking a fear that I haven’t explored and I’d be amplifying its paralytic power by giving it a name.
No, no, no. You don’t have “Writer’s Block.” You’re bored with what you’re writing right now. So write something else! You think what you’re writing stinks. You’re probably right; well, keep working and make it better! You don’t know how to continue? This means that you’ve encountered a problem and the problem won’t just resolve itself so you should just keep hammering at it.
