The project is tracking my diet, exercise, sleep, mood, productivity and a couple other misc. items.

I'm not sure exactly how to use the daily text entries yet, or if I'll use them in any direct quantified sense at all. One possibility is to run keyword searches to look for correlations between increased/decreased mood and the presence of increased frequency of certain items within any given day's/week's entry(s) (e.g. "my boss", "work", "girlfriend").

More than that though, I wanted to have a day-by-day narrative account available to check against my "harder" data to help provide clarity and answer questions in regard to interesting trends and correlations I observe.
