Even empowering beliefs will, at some point, become dis-empowering beliefs.
If you believe, for example, that you're a great writer, but the "universe" (or the deeper you) also thinks you'd make a great speaker, suddenly your belief that you are a great writer is in conflict. “I'm a writer, not a speaker.”
All beliefs, left unchecked, will, at some point, render us impotent, which is why we must be willing to consistently challenge them.
We need to find a way to go "beyond" belief.
Socrates told us, “Know thyself.” This means we KNOW who we are, and are unencumbered by beliefs about who we are.
Beliefs, whether they be about ourselves, other people or supposed truths like religion or unfounded scientific theories, must always be tempered with actual concrete and provable knowledge. It is OK to belief that one might make a great cook given enough training and experience but continuing to believe it disaster after culinary disaster is just self delusion. The cold, hard truth about ourselves is often very difficult to accept but not accepting it is what makes some people seem so phoney and mal-adjusted.
