I had no problem working for 15 hours straight when I was producing someone else, but I couldn't do it with my own songs. It took that moment of pointing the camera at myself to realize that it was okay to get lost in making my own music. I think before that I was scared of pushing myself to the point of staring into the abyss.
Faced with the sacredness of life and of the human person, and before the marvels of the universe, wonder is the only appropriate attitude.
