I've begun a couple of journals in the past but lose interest after a while.

Facebook is one way I document things, but I don't take facebook seriously.

I have friend who likes to text, and we text off and on all day. (I only see her 2 -3 times a year, and she lives about 2 miles away. It's her preferred method of communication.) I don't delete any of the texts, so I could consider that some sort of record of my days, her days and hour silly and serious thoughts.
