I found that most internal sabotages stem from simple causes. If you're shutting people off your life, then somewhere along the past you made the demand on the subconscious to stop trusting people at certain times. If you keep procrastinating, then you either had learned hopelessness or you're just not passionate enough. And if you can't be disciplined, and your thoughts go against you, then you are one of the following or a combination: the brain is overactive (you need some tea), you're paranoid or have OCD, you fail to see the big picture, you can't act in principle, you're too comfortable with the present situation, you find this struggle cute, or you need to cure your ADD/autism first because your mind is in the world of fantasy, or most likely you have low-self esteem and expectations in your choices.
