I gound the site in a backwards sort of way while reading about Hugh Prather the author of Notes to Myself: My Struggle to Become a Person. Prather was a student of Carl Rogers. Thirty years ago I thought Prather's book was pretty good - I'd have to read it again to see if it still resonates. You might find it interesting.

p.s. I noticed that Hugh Prather's book is on the S.F.Heart's reading list for wannabe hippies which probably explains why I was reading it 30 some years ago. Those were some groovy times man.
