I think we need another topic on this forum, dedicated to affective and general psychological variables 
In October, I tracked my personal values (money, career, learning, creativity, family, spiritual balance, etc.) three times a day, and then searched for some meaningful patterns and interesting insights:

Among the things I learned: which life priorities are the most and least important, how they change throughout the day (e.g., Creativity and Learning spike in the afternoon, and Relationships - in the evening). I will be also looking at the correlations between the priorities and other variables, like happiness, mood, work satisfaction, and sleep quality.
I was wondering if anyone else has attempted studying themselves from this perspective. I used Schwartz’s theory, but there are other ways (e.g, Rokeach’s values system, or Maslow’s hierarchy of needs).
