Self sabotage is when we are about to achieve something or change for better and then a contrary thought/emotion/action drives us away from the possibility of growth.
An example could be a worker, who is about to get a promotion (and who is aware of that) and then misconduct or suddenly quits after a petty reason.
Ultimately, self-sabotage is a protection tool generated in the brain, as the brain makes sure we don’t “move on” – which would consequently put our current comfort zone in risk. In other words, our brain is trying to defend us from danger of the “unknown” and very likely from dying (all according to neuropsychology!).
So instead of guessing that your self-sabotage is something that you have to avoid “doing”, exterminate from your life or keep on policing yourself all the time, understand why is your brain using such (protective) tool.
Why is your brain trying to keep you from moving to the next step?
If you get that job promotion, do you think you would have to work more, thus risking your ability to relax more?
Is your professional growth likely to bring in more worry on how to balance personal life and work life?
Is the destruction of an early relationship going to save you from being abandoned again?
Is loosing your mobile phone preventing you from speaking to someone you don’t want to?
Heal the cause that is activating your self-sabotage. And remember that self-sabotage is an unconscious protective tool.
