Questions about psychology and psychologists.

So I'm debating on what I want to study after high school (in grade 11) and have recently been interested in psychology. So I have a few questions: (All relating to South Africa)

• Psychology:
1. Is Psychology a competitive field to get accepted into?
2. Is it worth getting into psychology in the long run?
3. Is it difficult to get placed to become a psychologist?
4. What do you learn about in University?
• Psychologist:
5. Do psychologists get paid well?
6. Is it a safe job to do? (Regarding patients)
7. Is it hard to find a job after studying?
8. Is this job in demand?
9. What is the main component of the job?
Note: I have researched this field and job a little- but got many different answers, and haven't done a full-on research session since I'm in the middle of exams, and will do when I'm done.
