Gregory of Nazianzus was one of the early church fathers. Here are a few thoughts of his for your encouragement.
We are not made for ourselves alone, we are made for the good of all our fellow creatures.

Let us quake before the great Spirit, Who is my God, Who has made me know God, Who is God there above, and Who forms God here: almighty, imparting manifold gifts, Him Whom the holy choir hymns, Who brings life to those in heaven and on earth, and is enthroned on high, coming from the Father, the divine force, self-commandeered; He is not a Child (for there is one worthy Child of the One who is best), nor is He outside the unseen Godhead, but of identical honor.
