Keep making the effort. But the outcome is not upto you. Your boss believes what he wants to believe, over which you have no control.
Find things to do outside of the office. A job should not be the only place where one finds her identity. Ironically, when you have a richer life outside of the office, your life inside might get easier, because you no longer depend on validations from your boss, whose leverage over you will lessen and will have to find other ways to compensate.
As the saying goes, no one on her deathbed wished she had spent more time in the office.
