I'll give you an example.

Lets say that you love to cook meat at barbecues. You love all the aspects of the cooking: type of meat, time, taste, condiments...

Another guy comes and asks you to be the local meat cutter at a store, as a job.

Would you accept? My answer would be no (its just a hobby for me).

Also, you can do a vocational test. If every area has the same %, that means you could go study to any area, so just go for it.
