I read a long time ago that there are only two kinds of beginnings:
A stranger comes to town.
Someone takes a journey.
Funny enough, seems like every story-beginning I’ve seen can be boiled down to either of these phrases (or sometimes both!).
I can’t say as I’ve ever used this factoid to start a story, but I think it’s useful to know.
A few observation and much reasoning lead to error; many observations and a little reasoning to truth.
