The best job
There are a lot wonderful jobs. It depends always on the main features of a person how good he/she is in doing that job.
When I was a child I wanted to become an actor. My idea was that entertaining other people, making them laugh or cry must be the perfect job for me.
When I was a teenager I decided to become a doctor. Healing people, finding cure or miraculous medicine for the worst diseases must be the most wonderful job.
After I graduated highschool I passed all the exams at the University. I discovered that teaching children what is right and what is wrong, giving them information about life is just wonderful.
