Elmhurst, NY

I am currently a junior in highschool and I plan to major in industrial/orginzational psychology with a minor in business administration. I want to have a job in the human resources field. Is there any thing I should do or know to prepare myself for that field?

What after some exercises that will help me get better vocally as in clearer notes or any tips , and exercises to improve hand coordination and independence?

I am majoring in computer science. What kind of projects could you build?
