I just got an idea to overcome writing block, especially for the times when you got a vision or a detailed plan but don't know how to put it to paper because you just cannot find a good start. I've never heard this idea before but I cannot imagine I'm the first one to come up with something like that, but anyway, here I go:
>Write down scenes in your head in a somewhat chronological order
>Number them
>Throw a dice or use a random number generator to determine what scene to write
>Repeat until a good part of the novel is standing, then fill in the blanks
It's simple, it might turn out to be a shitty idea, but I'll give it a try. I'll let you know how it goes.
