The first step in the AA 12-Step recovery program is to admit that you have a problem. That's an attitude of humility. Other steps require confession, obedience, and even helping others along the way. That's the path of obedience. That's nothing new. These are God's ways from of old. Blessed is the one who will humble himself before God, and who will fully experience the blessings of God in following his paths of righteousness.
Consider this also: David sought to help others along the way of God's blessing. That's why we have this psalm. The fullest experience of God's blessings will come as we follow David's example of repentance, faith, obedience, and leading others as God give us opportunity.
