Hi Michael,
Paulett is right that studying a lot in your math and science courses and doing science projects will help you become a scientist.
Whether you end up becoming a scientist or choose another career, it is easier to survive tough economic times if you do well in school, graduate from college and/or learn many different skills. And while your education is very important, it is also important to learn how to adapt your skills and knowledge to unfamiliar situations. MacGyver may be a fictional character, but he is one of my heroes because he can adapt his skills to solve any problem (and because the actor who played MacGyver is from Minnesota!).
