Its like this... your "identity" or "ego" is based upon the structure of your mind. (I.E. your beliefs, thoughts, associations, knowledge, etc.)
So this pseudo mental self, is in reality no more than just a mental illusion. In truth, there is no-one behind the curtains (so to speak). Just pure empty conciousness, spirit, soul, or god (whatever you want to call it).
So this fake self (the ego) is constantly turning its wheels, cause if it doesn't it will cease to exist. The illusion of self will be no longer. So from that perspective, this fake self is continuosly running from its own death... the truth of its non-existance.
So your right when you say... thoughts (identity) = fear.
The fact that some people have positive structures of identity, say in a talent. Like picking up women... doesn't mean that the self is no longer in fear. It is just rewarded and emboldened in its structure, when such successes occur. But if you were to not pick up chicks for awhile, your identity would as far as this belief of self goes... would then be in question. So one of the pillars of the structure of your identity would then be in question (fear), if it no longer is as you think it is (I.E. Succesful w. PU).
So in this game... we just strive to create positive beliefs for our illusionary self, that cater to our goal.
But the real DJ, is one who transcends the whole illusion.
Who faces the truth of this fake self fearlessly, thus dissolving it, and realizing ones true power. This is the path of the warrior, the meditator, the DonJuan. So... while creating new beliefs that cator to your reality might be putting you on a track closer to your goal, you'll still be living an anxious life of fear in other ways. Something to point out would be that one could formulate beliefs that are parallel with the TRUTH, and thus direct themselves into this formless realm through them. Confidence for instance, would be a character trait of one who trusted in themselves. This quality would just be the energetic rewards of such a divine perspective. This would be the application of beliefs to assist the transcendance of the self into spirit.
The clarification is...Too many people are deluded into thinking its just about re-designing the structure of self. When the real path is just dissolving the fear-based self (the AFC)... to allow the righteous power of your spirit (the DonJuan) to emerge.
Peace'
