You may take all the right actions; yet sabotage your success by not believing it is possible because you have never done it before. Or you may have destructive beliefs, formed in the past and useful at one time, such as: I’m not capable, deserving, good enough, smart enough, or worse. Because it seemed true then doesn’t mean it still is. And at the time you formed it, it probably wasn’t even true, it was just your perception. There are many ways to interpret experiences. Some negative ways are: I’m a failure, or I never get what I want.
These statements were your take on the experience and were not true. But you believed them and stored them as statements of truth according to you. Someone else might have thought: I need to examine what didn’t work and fix it, or I’m proud of myself that I took the risk.
All these statements add positive reinforcement to this person’s belief system and they have a better chance of success next time.
