After tracking my daily sleep hours, caffeine and alcohol consumption, mood, weight, and exercise on and off for a year, I decided to see if this data could teach me anything.
And here it is: There’s a fairly strong negative correlation between the amount of caffeine I consume and the hours I sleep (-0.45, using Google’s CORREL() function).
Slightly more interesting: There’s a small positive correlation between my weight and my mood (0.24). The more I weigh, the happier I am, apparently.
But everything else is almost random. Maybe I’m just too consistent in my habits, but it seems like my life is a system in relative equilibrium, and I’m not seeing any obvious optimizations here.
