The Power of Achievement is the one I have, and I think it's v. good-- I actually took notes.
I've explored my share of SH/goalsetting/motivation stuff for personal and work reasons -- honestly, I think a lot of them aren't much to write home about. I tend to like the warm female approach better too-- Cheryl Richardson's seminars/books have been a big help to me.
But I really liked this CD set... maybe because the positive thinking stuff fits right into my belief system, or maybe because it comes to me at the right time. Maybe just because it's just great stuff?
