What should I major in?

<p>I'm having a bit of a life crisis. I'm starting grade 12 after this summer and I've never really known what I want to do so I've been researching about different jobs, and now I have too many things I want to do. Veterinarian, lawyer, pathologist, psychiatrist, and also anything in forensics (CSI type stuff and yes I realize its not the same in real life) or a forensic psychologist are my options. What could I major in to give me the most flexibility for the possibility to get into vet school, med school, law school or forensics if I don't have high enough marks for the previous 3. I have a 90 percent average in school currently.</p>
