Some of the best ideas I get seem to happen when I'm doing mindless manual labor or exercise. I'm not sure how that happens, but it leaves me free for remarkable ideas to occur.
My only writing ritual is to shave my head bald between writing the first and second drafts of a book. If I can throw away all my hair, then I have the freedom to trash any part of the book on the next rewrite.
If you start in the pit of despair with these profane, awful things, even a glimmer of hope or awareness is going to occur that's much brighter coming from this dark, awful beginning.
My way of being with people is probably incredibly unhealthy, in that I'll be incredibly social, and I won't write a word for maybe a year, and I'll just be with people, going to parties and soaking up stories, and just sort of recharging all of my ideas.
