These are three major mistakes you might encounter when embarking on the journey of removing PMO from your life.
Going cold turkey. When it comes to undoing the current structure of your ego and identity, it will take time, so be patient and try to avoid extreme changes of behaviour as these can often make your ego go into backlash mode and cause you to become more attached to porn.
Treating relapse as a failure or you going back to square one. Relapses are normal and a part of the journey towards success. If you choose to stay conscious and observe each relapse carefully, this can often give you more awareness that ends up helping you make more progress. So treat relapses with respect and pay attention when they happen.
Thinking a long streak means true progress. If you have a long streak, whilst having no internal emotional transformation or identity shift, then a streak is just a sign of good will power. Often, people will have a long streak, whilst still being very attached to PMO, and its this level of attachment that you must use as the yardstick of true change.
