I've been writing for 40+ years now, and I've come to the conclusion that, with very few, very limited exceptions, "writer's block" is doubletalk for either, "I'm too fucking lazy to put the effort into it" or "I'd like to write, but I'm afraid of how people will react, or scared of the process."
Writers write. That's all there is to it. Dilettantes get writer's block. Robert Heinlein wrote every day of his professional career, from the time he started publishing in the 1930s until the day he died. That doesn't mean he never took a day off, however; it means that when he was writing, he WROTE. Every day, whether it saw publication or not.
No ideas? Sit in front of a keyboard and write until you come up with one, or talk to one or more of the perverts here or elsewhere until you hear or come up with an idea you like, and then write about that. Having trouble with a piece of story? Write your way through it, or work on something else until your subconscious comes up with a solution. Too many ideas? There is no such thing. Learn to take notes, and write a damn story. Blank page phobia? See my comment above on "scared of the process."
I honestly hadn't written more than two consecutive paragraphs in a row (or, for that matter, in a week) for over six months until last night. Then I decided I was going to write, dammit, and I pumped out 8 1/2 pages between 11:00 PM and 9:00 AM, on a story I hadn't even looked at in over a year. The reason I "could" do that is that I DECIDED to do it, not because I "overcame writer's block" or any other self-defeating silliness.
I'd have said "empowering" not "harsh" bug I suppose it depends how you take it. If you hear "it's your fault you're not writing" then sure, it's harsh. If you hear "You are in control of this process. Stripped bare, you can choose to write or not" then more empowerment than anything. It is a choice, we each get to make it. Every minute, every hour, every day. You decide what to do. Of course, if you sit and write then what you write might be no good thus time, but you're still practicing the skill of writing and not training your mind yo be uncreative. Then again, if you hear "it's your choice, so stop whining and just do it" then it might also seem harsh. I don't happen to give a toss whether someone on the internet I'm not even close to thinks I should be writing or not though so again, it comes across as "You get to choose. What you choose is entirely up to you." Yeah, that's more empowerment.
