I am working on "me" this month (surprise, surprise

) and wanted to enlist the help of the smart and creative people that pop in here.
At the suggestion of the book "The Not So Big Life" I am putting together a sort of "owner's manual" or "operating instructions" for keeping this girl healthy and functioning. I know some of the periodic maintenance kinds of things I need to do (writing here, talking to a counselor, etc.) but am also trying to put together a list of things that I can build into Daily or Weekly life that will increase my chances of staying stable, happy, and healthy.
What are the things YOU do to keep your mind and body (and therefore mind) on an even keel? Do you take a multivitamin or some other supplement? Try to sit in the sun for 15 minutes? Take a half-hour of Me Time every day? Get X minutes of exercise? Write your emotions down in a journal? Talk to a certain friend who helps you stay out of the sticky emotions?
I'm interested in what other people do because I am simply dreadful at self-care, and I think it really contributes to me falling into these awful mental states.
This year, I want to get better.
Care to share what you do -- or what you know you SHOULD do?
Thanks, everybody
