Source of information about yourself

How well do you know yourself?
Where do you get information about yourself?

The way I see it, people don't have conscious access to their programs. They only have access to their beliefs about themselves. When they talk about themselves, they access this database where they store beliefs about themselves. They'll tell you who they are, what they are capable of, how they would behave in a certain situation, etc. But later, in a real-life situation, they behave differently. That's because in a real-life situation they execute their programs, not their beliefs about themselves. Those programs can be very different from their beliefs.

This is not an easy problem to solve. I still catch myself doing this sometimes. Although less and less often as I have better access to my programs. For example, I suppress parts of myself, because I have a belief that I've already dealt with this, so there shouldn't be anything there causing any problems. Or I deny having some negative emotions, because "I'm so spiritual, I shouldn't have any negative emotions". But I do. So I ask myself a question: "Why the hell would I access my beliefs about myself, actually believe in a false belief and try to deny an obvious problem causing a lot of tension, when I can access my programs and see what's actually going on?". Then I do that and I solve this problem.

Why do people store and access false information about their actual programs?
