I believe that the 4th and 5th Step from Alcoholics Anonymous are two of the most vital steps to progress. Without these, in my opinion, nothing changes.
All I can tell you is that the most frustrating part about living in my head has to do with all the garbage I carry around from the past and its power to still control and run my life. Decisions propelled by past experience and fear have inevitably caused me and other harm in my life and led to self-destruction. I personally can't take that anymore and feel that these are the steps to my freedom.
