The first answer should be correct, as none of the others make any sense.
In my opinion, yes, people should pick an occupation based on their personal interest. This is because if they start an occupation and it is not something you want to pursue, you will more than likely not be happy with what you do. It is better to go into something that you are sure you will enjoy so that you will be happy!
