i know it's basic but keeping a daily journal has been one of the most grounding things in my life. you don't need to shell out $$$ on a travelers' notebook and a snazzy pen, but just repeating the daily act of physically writing your thoughts down is a wonderful thing. i keep a daily recollection/diary sort of thing along with a sort of freeform commonplace book where i jot down thoughts or lyric ideas or cool words i read and had to look up definitions of. it's nerd shit but the sort of positive affirming nerd shit that everyone needs at least a little bit of. also the amount of stuff you forget over the course of a week/month/year is astounding -- doing this is fun in part because you can read through your past entries (good and bad) again with fresh eyes.
