Surveys, interviews, and such

For my paper, I plan on taking surveys from college students and maybe even try to contact kids from my high school and see if there's a difference in the way high school and college kids spend their time. By doing that, hopefully I can see if there's an emotional difference between the two types of schools.

Questions I can ask may be:
How often do you do school work? In doing so, how often is that last minute?
How often would you say you're stressed when doing school work? Why?
Do you find yourself more productive after you've spent time with friends and then doing homework? If so, why?
How often do you find yourself laughing or joking around throughout the day? Would you assume that you produce better work when you're happy?

I also hope to maybe talk to a therapist and maybe see if they see a difference in patients' work and lifestyle when they're happier. Also, maybe even a teacher or professor to see if they can tell by school work whether a student was stressed or upset when they finished an assignment and see if they know that that affected their work or not.
