What is the difference between
1. job / employment / occupation
2. profession / trade / vocation
3. works/ labours / toils

1. Job means that you can work for money and other things | employment means that you have a job and you're working | occupation means that there's too many people in that job to get employed.
2. Profession means that your great at something | Trade is pretty obvious, you're trading something. Like trading food for money | Vocation means you have a very strong feeling about something, just like a purpose for doing something.
3. Work is pretty much just doing stuff. Cleaning your house, doing laundry, things like that | Labor is the same as work, your being productive and doing stuff | Toils, same as work and labor, it's just means your working extremely hard.

The answer is !
