I agree with Thio here, you signed a CONTRACT.
That's like Lebron James signing a Multi-Million Dollar Deal one Sunday morning, but turning around on Monday Morning and saying
"Well, I'm not feeling this team, so I am gonna go with the other team that offered me this."
You just can't walk out of a Contract, there's legal obligations, most contracts say you need to upload a MINIMUM amount of videos, etc.
People always seem to want out of a Contract when they feel they aren't getting the pronation they deserve, lack of CPM, etc., when in reality, to be successful you need to promote yourself, and the more you promote YOU, the higher your CPM can climb as Advertisers/YouTube/Google/Networks all see the kind of traffic you bring in (whether monetizable or not).
If you signed for a year then stick it out, worse thing that can happen is all of a sudden you lose subscribers or you lose views.
