Definitely agree on having a Thing that says "it is time for words now"; I don't do it all year round, but during NaNoWriMo I have a lovely cast iron teapot and I fill it with my favorite green jasmine tea and slowly consume it while I'm writing.

Another possibility is a song you can associate with starting a writing session, or a particular scented oil or candle. I've used both of those.
