King David experienced great highs in his life like uniting the kingdoms of Israel and Judah, defeating a giant in battle, and bringing the ark of the covenant back to Israel. He also experienced many lows such as, having Saul throwing spears at him in the royal palace, running for his life from cave to cave, and being exiled from his kingdom by his own son. Through all of that in Psalm 16 we see David's conclusion - everything he ever needed was found in the presence of God. This is still true for us today! As David writes in Psalm 16, the path of life, fullness of joy, and pleasures forevermore are all found in God's presence.
