This is a link to some free to view talks from the Avaiya University and the content is about Self-esteem.
I haven't listened to many, as there was another Conference on Trauma that I was watching, but I did listen to the talk by Mark Smith, and I found his to be very good - his personal story touched me, and I thought he spoke well.
I am sure the others will hopefully be good too - I may have watched others, but I am rushing a bit just to put this info up, as I have limited time at this moment. I just had the E-mail telling me they were re-playing these talks for this weekend for free.
Hope :)
