Set Up:
You will need pen, paper, and a bit of uninterrupted time. It's easier to keep a diary if it's limited to about 6 minutes, and if you have specific things to write down. Once you start the video you'll spend two minutes writing down the things that happened yesterday, then two minutes writing down what you saw, then a minute writing down what you heard said, and about 90 seconds drawing a quick and simple picture of something you saw yesterday. Do this every day for a week then read over your pages. Start to notice what it is you notice as you go about your day.
