I'm begining a new experiment.

At regular intervals through the day, I give my current mood a rating out of 10. The scores across each day are averaged, and then I graph them. Here are the results for the past few days.

Some initial qualifications:

- averaging for each day probably hides a lot of the variability. I'm rarely sad or elated for the whole day. However, since I sometimes miss the scheduled data entry time, or enter it in late, i felt that an average might be better.

- The rating is an evaluation of the pleasentness of my mood. Now, some of you might well point out that mood doesn't vary along a single dimension. Feeling fatigued is pleasent late at night before you go to bed, and feeling alert is pleasent in the middle of the day. I'm not dealing with these issues. I'm collapsing everything down into one subjective rating

- The face validity of the question I ask myself - "how are you feeling?" - may be way too high. I may distort my rating and try and aim for a certain score. Also, the act of observation may affect my mood. But, that's fine with me.

I'll keep you posted
