The first step of humility, then, is that a man keeps the fear of God always before his eyes (Ps 35 :2) and never forgets it. He must constantly remember everything God has commanded, keeping in mind that all who despise God will burn in hell for their sins, and all who fear God have everlasting life awaiting them. While he guards himself at every moment from sins and vices of thought or tongue, of hand or foot, of self-will or bodily desire, let him recall that he is always seen by God in heaven, that his actions everywhere are in God's sight.
The second step of humility is that a man loves not his own will nor takes pleasure in the satisfaction of his desires; rather he shall imitate by his actions that saying of the Lord: I have come not to do my own will, but the will of him who sent me (John 6:38).
The third step of humility is that a man submits to his superior in all obedience for the love of God, imitating the Lord of whom the Apostle says: He become obedient even to death (Phil 2:8).
The fourth step of humility is that in this obedience under difficult, unfavorable, or even unjust conditions, his heart quietly embraces suffering and endures it without weakening or seeking escape. For Scripture has it: Anyone who perseveres to the end will be saved (Matt 10:22), and again, Be brave of heart and rely on the Lord (Ps 26 :14).
The fifth step of humility is that a man does not conceal any sinful thoughts entering his heart, or any wrongs committed in secret, but confesses them humbly. Confess to the Lord, for he is good; his mercy is forever (Ps 105 :1; Ps 117 :1).
The sixth step of humility is that is being content even with the lowest and most menial job.
The seventh step of humility is that a man not only admits with his tongue but is also convinced in his heart that Jesus is Lord.
St. Bernard also had 12 Steps to Humility. You can find them by a Google search.
Therefore, AA was not the first with 12 Steps!
