Sometimes I find that the beliefs that I think and journal about are not always the ones that I act on. I have mentioned this phenomenon in greater detail in this post.
I believe this is a common situation, because a belief that makes sense to us logically will not necessarily govern our actions as much as years of conditioning will.
So how can you know what your real beliefs are if what you talk about is not in line with how you act?
You have to review your past actions and ask "what belief would caused me to do that?"
It's a pretty simple exercise, but the real effectiveness comes in the application of it. Taking the time to compare your intellectual beliefs and your core beliefs will help you to become a more congruent person.
It may also help you to learn more about the beliefs that are guiding your actions. You can then use this valuable information to help determine whether these beliefs are moving you closer or farther away from you goals.
