Some brainstorming ideas I have so far are:
1: Hours of studying, Where studying takes place, For what classes
2: What food I eat in a day, All week, What times in the day, How many calories, Am I alone or with company, What mood am I in when eating
3: Where I spend money, How much, What time of day, Is it a need or want, What mood am I in when spending
4. What music I'm listening to (genre), What time of day, How long per song, Driving, walking, sitting, cleaning
So far I like the look of using different forms of maps to convey messages
