Here we go.  A week into rehearsals and, in traditional fashion, I've hit my usual paranoia, doubting myself, certain I've tried the patience of my fellow cast members, and so on and so forth.  The regularity with which this always afflicts me would be quite funny, if it wasn't so annoying and debilitating.

What is it about the human psyche, that makes it so much easier to latch on to your own solitary low self-opinion, than all the nice things other people have ever said about you?
