/lit/ - Literature

I'm reposting from the /tg/ one since I didn't realize /lit/ had a wbg now. Both of my settings I plan to write stories in so it's better to ask here.

Two questions. Because I have two settings, one far more developed than the other, to the point that I *could* write plenty of stories in the larger one by now.

1) (the less developed setting) For a space warship that uses coilguns as its primary armament (along with missiles, and lasers for point defense) what turret configuration is the best? Single, double, triple, or quadruple? I'm leaning toward quadruple for the "hero" faction (the one the protags are part of) and double for the villain faction because quad turrets are badass.

2) How the fuck do I get myself to, you know, write? I enjoy it once I just *start* but I quite often can't can't bring myself to.
Also if anyone has any ideas for keeping track of specific spells in a magic system for easy reference that would be helpful as well.
