TU, thanks for pointing out that getting caught up in a concept in the book and not understanding it IS the AV voice telling me...... "see, you're not getting it. This is more complicated than it seems. You might as well just give up now because you'll never be able to get it until you thoroughly understand the never now thing, you'll never get anything so just give up now and give yourself a break". I didn't think of it that way until you pointed that out. Thanks for that.
