Writer's Block-fact or fiction

I was just reading a book that was talking about writing and editing and all that good stuff, and I found that the author had a lot of strong opinions about things. One of the major things is that he doesn’t believe in writer’s block. There is a controversy on that, and I guess it’s still up in the air, but it’s a good point. He believes that writers use ‘writer’s block’ as an excuse to be lazy; that it’s actually just a way of saying that a writer has lost motivation or focus. Honestly, I don’t believe that. I’m a writer who has trouble with it and it’s not because I’m lazy or unenthusiastic. It’s because I can’t see my story in perspective. I can’t write with the normal flow or get right into the snappy dialogue. Still, I sit down at my computer and try. Every time, I try. Some days, nothing at all. But the act of trying even when it’s hard is proof against any laziness. What I think writer’s block is isn’t an excuse, but a term that writer’s use to say that the flow just isn’t coming like it should. It’s a mental block, an obstacle that truly does exist in one form or another. I suppose someone could use it to mean they feel like being lazy, but it’s a general term. For example, when you say you feel sick, you could mean you have a cold, or you could mean that you wish your brother would stop picking his nose while you’re eating dinner.
