Well, the problem lies in the question, really. You don't complete the Steps, not really!
Option 1: Practise Step Twelve as a way of life (supported by the preceding eleven Steps, especially Steps Ten and Eleven).
Option 2: Try to live a life run on self-will (sex, money, power, prestige, comfort, thrills, appearance).
Option 3: Start finding fault with your home group, your sponsor, and your spouse. Gossip.
I've tried all three, and Option 1 is definitely the best.
