Don't set resolutions. Get clear on your values. Set dreams. Follow them and never give up. Fail once. Fail again. Fail some more. It's scary. But extraordinary is called extraordinary because it's a life outside of the ordinary. It requires going that "extra" mile that most people don't bother taking because of reasons I won't go into here.
As the poet Rumi suggests, we are all like fish driven by thirst. Unaware that we are already immersed in the thing we seek, we flail around helplessly when all we need to do is swim. As I see it, failure is merely the first stage of success. And if we are living an authentic life, happiness unfolds by itself.
