What is your best way for breaking the block? If you don't have a 'best' way, what do you find has broken your block(s) in the past?
Poking around on the internet.
Reading or watching something that's not similar enough to what I'm working on to get in the way, but is close enough that my characters will have reactions and opinions.
Starting something completely different. (Not hugely recommended; I think everybody accumulates things they astart and do not finish, but it's all too easy to get cuaght up in this and never finish anything.)
And, of course, Conceptual Guilt-Judo 101; find something I can persuade myself I need to be doing
more, so that I can convince myself that I am actually
goofing off when I go back to write on whatever it was, and therefore it does not have the psychological pressure of being blocked.
