We need the basic humility to acknowledge our sinfulness and recognize Gods existence, absolute superiority, and of our need for Him. And this can be a tall task. But if we overdo that we’re entering the realm of shame/ self-hatred, which is destructive, nihilistic. It’s a balancing act in a sense because God also loves and values man immensely. We need to know of our worth, or potential for it anyway, at the same time. From the CCC:
356 Of all visible creatures only man is “able to know and love his creator”.219 He is “the only creature on earth that God has willed for its own sake”,220 and he alone is called to share, by knowledge and love, in God’s own life. It was for this end that he was created, and this is the fundamental reason for his dignity:
What made you establish man in so great a dignity? Certainly the incalculable love by which you have looked on your creature in yourself! You are taken with love for her; for by love indeed you created her, by love you have given her a being capable of tasting your eternal Good.221
357 Being in the image of God the human individual possesses the dignity of a person, who is not just something, but someone. He is capable of self-knowledge, of self-possession and of freely giving himself and entering into communion with other persons. And he is called by grace to a covenant with his Creator, to offer him a response of faith and love that no other creature can give in his stead.
358 God created everything for man,222 but man in turn was created to serve and love God and to offer all creation back to him:
What is it that is about to be created, that enjoys such honor? It is man that great and wonderful living creature, more precious in the eyes of God than all other creatures! For him the heavens and the earth, the sea and all the rest of creation exist. God attached so much importance to his salvation that he did not spare his own Son for the sake of man. Nor does he ever cease to work, trying every possible means, until he has raised man up to himself and made him sit at his right hand.223
