Belief versus Fear: Who Wins?

I'm just trying to get to the heart of the matter. What helps us most? Analyzing our beliefs or managing our fears?

It's gotta be belief. Belief is the only reason we are able to choose between action and inaction. We don't have to agree with the belief. We only have to believe that the belief is necessary. Belief has nothing to do with the truth which is why antelopes run for their lives instead of fight for their lives. An antelope stampede against an attacker is a powerful thing yet antelopes run because they believe running is their only choice. Likewise, a stampede of beliefs such as, I am strong, I have value, I am special, I can do this, I should do this, I can learn to do this, etc. can turn away the strongest fear. Belief is what controls us, not fear.

It's gotta be fear. No matter what we believe, fear is either a motivator or demotivator. We remember fear most. We consult with fear most. Fear is more powerful and important because it is what surfaces first and imposes its own belief upon us. Fear is a master of disguise. It presents itself as all the things that seem right and sound good. It presents itself as logic, reason, caution, safety, security, protection, self-preservation and so on. Fear is what controls us, not belief.

Which one is it really? If it all came down to belief and fear, which one would be the deciding component of our life? Which one is most important to our personal growth? Which one is most important to our personal defeats or victories? Belief or Fear? Are we better off analyzing our beliefs or managing our fears?
