I don't think this is the place to look to in order to quit your job and make this a full time living. The site does reward users for creating content and there are some users who earn a hefty mount of money doing so, but that is not the average user.
I feel Steemit is really for those who truly enjoying creating content and sharing it with others as a hobby. The ability to receive earnings is a bonus, but I don't think it should be the basis in someone joining the community.
