I just re-read this more carefully.

The inference is that high levels of perceived self-efficacy would be for example akin to the natural whose reality is based on past performance accomplishments, vicarious experience, verbal persuasion and physiological information. That person would therefore be that much more effective due to the non existence of barriers in their perception that having a high threshold in self-efficacy would facilitate, or at least those barriers being high enough to matter much less.

So I suppose my question is, this describes theory what's going on, OK I'm with you so far, but how does one seek to actually raise their own level of self-efficacy consciously? Which I imagine is the same question as how to change one's subconscious beliefs...
