Did the excitement of the thought of writing this come from my dislike for the homework that is now being postponed, or did it come from my like of writing?

What do I do when everything I do seems to have two motives: one selfish and one selfless, one lazy and one ambitious, one bad and one good? Should I just expect that my sinful nature is secretly controlling me and hiding itself behind a righteous façade, or should I expect that God is drawing me nearer by revealing the conflict within me(see Romans 7:15-25)?
