One thing I didn't really get from Wolfram's analysis is how this data drives decisions. It's neat to look at, I read the section on email and skimmed the rest, but I don't see how consequential it is. I hope to use my analysis to decide whether journaling is improving my mood and whether I should focus more or less on goals. In November I'm also going to start marking approximate exercise time and grade myself 1-5 on diet. If sentiment analysis plots work, that can help me dial in exercise and eating habits. That's the idea any way.
I'm tempted to wear a fitness tracker, that would give more data and could automate data collection for steps, exercise, and sleep - but I find the wrist trackers uncomfortable to wear.
