Doing the steps by yourself is really hard, I suggest a sponsor or another 12 step person to help you through them. The steps should be thorough and honest, but they don't have to be perfect! Perfectionism stops lots of people. Also, don't rush just to "finish". There is no time frame, however, don't use that for an excuse to avoid doing them. Long term sobriety is unlikely without doing these steps. (Clean and sober since '94, have seen untold thousands of addicts go through this process). Good luck!
