I'm a massive fan of a diary. I usually use my phone as well, but this year I'm running both a phone and paper diary, but the phone is my master diary.
I also have a whiteboard calendar which I write things on because otherwise Matt would forget what we have on for the week.

I won an MP3 player at the gym at lunch today and it made my day! I filled in one of their surveys at the start of the year but I didn't realise there was a prize draw and wouldn't you know it, I got first prize! I was having a crappy day before that!
