How many times have you said any of these things?
“I have no ideas”?
“My mind has gone blank”
My personal favourite is: “I just can’t think of anything to say”.
I call it Blank Page Syndrome (so do other people—I didn’t invent the term).
It really annoys me when people say “I have no ideas”. It shouldn’t annoy me I _know_, but it does. It annoys me even more when I say it _to myself_.
Why does it annoy me more than the last season of Game of Thrones?
The simplest reason is: you saying “I have no ideas” isn’t true.
It’s never true.
