4. I make playlists and listen to them before and as I'm writing for that character.
8. People who see someone and immediately think "I must be better than that person at their particular strength!" I usually have flaws in my characters so they have places other people can excel easily!
Example: my mad genius Eiko Takashima is a polymath, but even so, she can't cure cancer, she's made some really bad decisions and holds grudges. She's also kind of crazy, so she may not be 100% reliable.
12. Getting into another headspace and seeing things from it.
2. Tabletop! I've been playing D&D since 1980 (I'm old that way), and other games, and then writing stuff, and then got into online RP on MUSHes in the mid-90s, and then LiveJournal in 2006 on sages_of_chaos, and then to dear_multiverse.
10. not really. I mean, I like a good character romance arc, but it's got to be part of things, not the entire thing.
11. Most of my characters have turned out to be some flavor of queer, but that's about it.
