Compare your ‘strategies’ for reaching a good decision with how you arrived at a bad one. There will probably be significant differences. Much of your processing may be unconscious so you will get better results working with a skilled NLP practitioner.
Check what kind of mental images you are using in your decision-making process. NLP therapist Andrew T Austin suggests still pictures lead to bad decisions, moving pictures to better ones (because it’s easier to see the consequences of the decision).
Remedy: If your mental pictures are largely still, try making them into movies.
