The only tried and true way to stop self sabotage is to rein the conscious mind into the present moment, focused on here and now. Now is the only point of choice. Frantically running hither and thither focusing on what I did not get in the past or scheming how to get “it” in the future causes the self limiting programs to run automatically.
I have started chanting. A mantra repeated over and over is paralyzing to the cerebrum. Unfortunately I can’t go through the whole day mumbling and counting beads.
