I think I would start by making a basic questionnaire you want to use, and then interview people in various fields. The interviews will use up some of the hours. You can do them by phone, e-mail, videochat, or in person. Do several, across the various fields that are of interest to you. Then pick about 3 people to shadow, perhaps for half a day each (3-4 hours)
Obviously you can't shadow a person doing counseling. however, I've had "shadows" sit in when I had Dr appts - the dr introduces the shadow, and asks me if it is okay. So, there are possibilities, probably in some of the less deeply-personal areas. You could probably shadow a career counselor in college, for example. The clients are adults, and can give their own consent. Doing it with minors (in high school) would be more difficult, due to privacy and consent issues. You may also look at interviewing somebody in marketing. I have never worked in that field, but, I consider it to be like an applied psychology - you are trying to make somebody buy something! Depending on your age, and the requirements, you may be able to do a ride-along with a police officer. A lot of social skills are required to do this work! As a retired officer, I will tell you that making an arrest takes a lot of time (paperwork) and it is much easier to resolve petty spats in some other way. When it is between family, friends, or neighbors, as an officer you know it will be an on-going situation if you are not able to get to the heart of the matter. Or, perhaps someone at the YMCA , scouts, or other youth program. Also consider interviewing a pastor or someone at a church. While they cannot divulge confidences, they will be able to tell you, in generalities, some of the issues they deal with!
As to the questionnaire, here are some questions. You don't want to ask too many, probably 5-7, so there is time to discuss the answers. These are just suggestions to get you started, feel free to modify!!
- How long have you been a __________ and why did you choose to become a _________?
- What training and education are required for this position?
- What do you like the most about your job?
- What do you like the least about your job?
- What advice would you have for a young person considering this line of work?
- Can you tell me about one of your most memorable moments, where you feel you really made a difference in someone's life?
Best of luck!
