*I am incompetent at most of the things I do in life. I am a faker and a hypocrite for pretending I am knowledgeable or competent in any area of my life, and eventually I am bound to be found out.

Yeah, I've got this one pretty badly too; I blame grad school for it. On the upside, I've been trying to channel it into improved financial responsibility (i.e. saving like a fiend, so that when I *am* found out, I'll be financially independent, and it won't matter anymore).
