There so many self-help books that do little other than attempt to boost the promoters stature and financial resources. I would suggest to do the opposite, stop the quest for external knowledge in favor of acquiring self-knowledge, stop buying all products that make bold promises cultivate your fear when you understand what it is you are afraid of and why, it will be enough to deal directly with what is holding you back no book or speaker is going to be able to do that for you.
