I have seen the videos (2 of them) I can tell how in love Dr. Barret is.  I think tthat is the real key to learning, as she mentioned herself in the video.  Once you (the learner) reaches that point every thing is possible. I compare learning to my  students with falling in  love, you call the person, look for her/him, do whatever it takes to be close to him/her, and so on. The final and only objective  is to be "learned" /  "recognized" by this special person.  Well, I will continue with the thinking process, let see if I can come up with something more academic. So long!!!!
