Self sabotage?
Feed on knowledge. Make deliberate, intensive investments into your Spirit man about the Truth. It’s a fight of active brainwashing, so read books, listen to podcasts, study Scriptures, journal extensively, put up notes about what God is saying to you – put them up where you can see them, step into communities of people who believe that you are already who you think that you want to become, and allow them to validate you (and when they do, don’t object, just let it sink in. You’d grow to believe it, and you wouldn’t need the external validation any more)
Thank God for growth, and get specific in your Thanksgiving
Then….
Break your action plan down into tiny steps and commit to taking a step each day/week/month
You don’t beat self-sabotage by confronting it (turning it into your complete focus would be counter-productive, actually). You work around it until it doesn’t exist any more
